    　View Summary

    Mishandling and disposal of post-harvested phytoremediation biomass results in secondary pollution. Biochar production is one of the available technologies for processing post-harvested phytoremediation biomasses. The main objective of this study was to assess the potential adsorption of PO43- and NO3- ions from a binary solution by ZnCl2-activated phytoremediation biochars. The biochars were activated using ZnCl2 and analyzed for specific surface area, pore size, volume, surface morphology, point of zero charges (pHpzc), surface functional groups, and elemental composition. Subsequently, the adsorption potential for PO43- and NO3- ions of the activated biochar was investigated. Activation of phytoremediation biochars led to the development of new micropores and increased specific surface area range from 1.62-4.72 m2 g-1 to 4.75- 55.50 m2 g-1. ZnCl2 activation reduced the pHpzc values of Cymbopogon citratus, Cymbopogon nardus, and Chrysopogon zizanioides biochars (BCL2, BCC2, and BCV2) from 9.75, 9.50, 9.62 to 5.72, 5.51, and 6.23, respectively. Activated Chrysopogon zizanioides biochar (ACBCV2), activated Cymbopogon nardus biochar (ACBCC2) and activated Cymbopogon citratus biochar (ACBCL2) showed maximum potential phosphate ion adsorption capacities of 115.70, 101.74, and 270.59 mg g-1, respectively. ACBCL2, ACBCC2, and ACBCV2 indicated maximum potential nitrate ion adsorption capacities of 155.78, 99.42, and 117.71 mg g-1. BCC2, BCL2, ACBCV1, ACBCV2, and ACBCC2 best fitted the Langmuir linear form 1 model during NO3- adsorption. The results obtained in this study showed that ZnCl2-activated phytoremediation biochars have the potential to remove PO4 3- and NO3- ions from PO4 3- and NO3- ions binary solution.

  • Mitigation of bromine-containing products during pyrolysis of polycarbonate-based tetrabromobisphenol A in the presence of copper(I) oxide

    　View Summary

    Polycarbonate (PC) is an engineering thermoplastic that is widely used in electrical and electronic equipment. This plastic often contains tetrabromobisphenol A (TBBA), the most common brominated flame retardant. Thermal degradation of the PC-TBBA leads to generation of numerous bromo-organic products in the pyrolytic oil, hindering its appropriate utilization, as well as corrosive hydrogen bromide gas. The purpose of this study was to experimentally investigate and compare the pyrolysis products of PC-TBBA and PC-TBBA + Cu2O at various temperatures, with an emphasis on the yield and distribution of brominated compounds. In pyrolysis of PC-TBBA + Cu2O, at the maximum degradation temperature (600 °C), as much as 86% of total Br was trapped in the residue, while 3% and 11% were distributed in the condensate and gas fractions, respectively. In contrast, the distribution of Br from non-catalytic pyrolysis of PC-TBBA (600 °C) was 0.5% residue, 40% condensate, and 60% gas. The results of this study revealed that in the presence of Cu2O, organo-bromine products were most likely involved in Ullman-type coupling reactions, leading to early cross-linking of the polymer network that efficiently hinders their vaporization. HBr in the gas fraction was suppressed due to effective fixation of bromine in residue in the form of CuBr.

  • Comparison of sewage sludge mono-incinerators: Mass balance and distribution of heavy metals in step grate and fluidized bed incinerators

    Waste Management   105   575 - 585  2020.03  [Refereed]

    　View Summary

    We investigated the distribution of 18 elements including non-volatiles (Al, P, Ca, Fe, Mg, K, Mn, Cu, Na, Cr, and Ni), semi-volatiles (Zn, Pb, Ag, As, and Cd), and volatiles (Hg and S) and compared their behaviors in two types of full-scale sewage sludge mono-incinerators, namely, a step-grate stoker (GS) and two fluidized bed incinerators (F-types), with the same feed sludge. Most of the non-volatile elements were enriched five-fold in all incinerated sewage sludge ash (ISSA), while the volatile S and Hg were barely enriched in ash due to the combustion components generated in the gas phase. While the semi-volatile elements were also enriched five-fold in the F-types, a different enrichment behavior was observed in the GS. Boiler and multi-cyclone dust in the GS showed higher enrichments of Pb and Cd compared to ash due to the combined effects of lower temperature and smaller particle size. Compared to the F-types, the GS generated ashes with lower toxicity as the major component (99.7%) and hazardous dust as the minor component. In the future, more attention should be paid to grate stokers in terms of recycling ISSA.

    　View Summary

    This study focused on the thermal degradation of polycarbonate (BrPC) and high-impact polystyrene (BrHIPS), containing different brominated flame retardants. The evolved inorganic bromine was utilized for the separation of metals present in electric arc furnace dust (EAFD). The thermal degradation of BrPC generated inorganic gaseous HBr (69%) and condensable Br2 (31%). The bromine evolved from BrHIPS was detected almost entirely in a condensed phase as SbBr3. When mixed with EAFD, the evolved inorganic bromine reacted immediately with the metallic components of zinc and lead, but not with iron. The best bromination efficiencies were obtained during the isothermal heating (80 min at 550 °C) of the mixtures at mass ratios of 6:1 and 9:1 w/w under oxidizing conditions. The achieved brominating rates reached 78 and 81% for zinc and 90 and 94% for lead in 6:1 and 9:1 BrPC:EAFD, respectively, and 47 and 65% for zinc and 67 and 63% for lead in 6:1 and 9:1 BrHIPS:EAFD, respectively. The oxidizing condition favored complete vaporization of the formed bromides.

    　View Summary

    The purpose of this study was to select the most effective ionic liquid (IL) extraction solvents for NdF3 using a theoretical conductor-like screening model for real solvents (COSMO-RS) for predefined NdF3-IL systems. Chemical potentials of NdF3 were predicted in 900 hydrophobic ILs. On the basis of these predictions, a number of IL ions showing a significant decrease in their chemical potentials were selected. Considering the calculated physicochemical properties of ILs containing these specific ions, the most effective IL extraction solvents for liquid-liquid extraction of the salts were proposed. This study shows that the COSMO-RS approach can be applied before conducting extensive experiments to quickly screen the affinity of any rare earth element for many IL systems.

    The purpose of our study was to select the most effective ionic liquid (IL) extraction solvents for NdCl3 and DyCl3 using a theoretical conductor-like screening model for real solvents (COSMO-RS) based on quantum chemistry and the statistical thermodynamics of predefined NdCl3-IL and DyCl3-IL systems. The thermodynamics of the extraction process were predicted with the COSMO-RS method.NdCl3 and DyCl3 were considered in 4400 different ILs. As predicted, the chemical potential values of both NdCl3 and DyCl3 decreased significantly in systems with ILs based on the cation of dodecyl-dimethyl-3-sulfopropylammonium and the anions of bis(2,4,4-trimethylpentyl) phosphinate, decanoate, and benzoate.Considering the calculated physicochemical properties of the ILs containing these specific ions, the most effective IL extraction solvents for liquid-liquid extraction of the salts were selected. Experiments confirmed the high extraction efficiency of the ionic liquids chosen based on the COSMO-RS predictions.The COSMO-RS approach can be applied before extensive experimental tests to quickly screen the affinity of any rare earth element (REE) for a large number of IL systems, if only the physical dissolution of the REEs is considered.

    Journal of Hazardous Materials   278   25 - 33  2014.08  [Refereed]

    　View Summary

    In the present work we investigated the fates of zinc, lead, and iron present in electric arc furnace dust during thermal treatment of the dust with tetrabromobisphenol A (TBBPA) and tetrabromobisphenol A diglycidyl ether (TBBPADGE). Mixtures of these materials were compressed into pellets and heated in a laboratory-scale furnace at 550. °C for 80. min, under oxidizing and inert conditions.The solid, condensed, and gaseous-phase products were characterized using an array of analytical methods: scanning electron microscopy, X-ray diffraction, electron probe microscopy, inductively coupled plasma, ion chromatography, and gas chromatography.The results indicated that heating the mixtures under specific conditions enabled high separation of zinc and lead from iron-rich residues, by a bromination-evaporation process. In the case of TBBPADGE, a maximum of 85% of zinc and 81% of lead were effectively separated under the above conditions.The process is based on the reaction between the highly reactive HBr gas evolved during thermal degradation of the flame-retarded materials with zinc (ZnO and ZnFe2O4) and lead in the dust, followed by complete evaporation of the formed metallic bromides from the solid residue. © 2014 Elsevier B.V.

    　View Summary

    In this paper, the bromination reaction between lead oxide and hydrogen bromide originating from the thermal decomposition of tetrabromobisphenol A (TBBPA), under inert and oxidizing atmospheres, was investigated, using a laboratory-scale furnace. The results obtained under inert conditions indicated that bromination of PbO proceeded simultaneously with debromination of TBBPA, with an average effectiveness of 69% (max. 80%). Volatilization of the formed PbBr2 began at 315°C, intensified at 750°C, and reached 98% at 850°C. The formed organic char served as a source of carbon for reduction of the unreacted lead oxide to metallic lead in the range 315-750°C. Additional experiments conducted at selected temperatures under slightly oxidizing (5vol% O2) and quasi-atmospheric (20vol% O2) conditions showed no significant effects on bromination-evaporation of lead in the studied mixture. However, in isothermal treatment under quasi-atmospheric oxygen levels, complete vaporization of the formed lead bromide was obtained at a temperature of only 650°C. © 2013.

  • Distribution of copper, silver and gold during thermal treatment with brominated flame retardants

    Waste Management   33 ( 9 ) 1835 - 1842  2013.09

    　View Summary

    The growing consumption of electric and electronic equipment results in creating an increasing amount of electronic waste. The most economically and environmentally advantageous methods for the treatment and recycling of waste electric and electronic equipment (WEEE) are the thermal techniques such as direct combustion, co-combustion with plastic wastes, pyrolysis and gasification. Nowadays, this kind of waste is mainly thermally treated in incinerators (e.g. rotary kilns) to decompose the plastics present, and to concentrate metals in bottom ash. The concentrated metals (e.g. copper, precious metals) can be supplied as a secondary raw material to metal smelters, while the pyrolysis of plastics allows the recovery of fuel gases, volatilising agents and, eventually, energy. Indeed, WEEE, such as a printed circuit boards (PCBs) usually contains brominated flame retardants (BFRs). From these materials, hydrobromic acid (HBr) is formed as a product of their thermal decomposition.In the present work, the bromination was studied of copper, silver and gold by HBr, originating from BFRs, such as Tetrabromobisphenol A (TBBPA) and Tetrabromobisphenol A-Tetrabromobisophenol A diglycidyl ether (TTDE) polymer; possible volatilization of the bromides formed was monitored using a thermo-gravimetric analyzer (TGA) and a laboratory-scale furnace for treating samples of metals and BFRs under an inert atmosphere and at a wide range of temperatures. The results obtained indicate that up to about 50% of copper and silver can evolve from sample residues in the form of volatile CuBr and AgBr above 600 and 1000. °C, respectively. The reactions occur in the molten resin phase simultaneously with the decomposition of the brominated resin. Gold is resistant to HBr and remains unchanged in the residue. © 2013 Elsevier Ltd.

    　View Summary

    DSC, TG, and TG.MS techniques were used to investigate the reactivity of PbO and Fe2O3 with HBr from thermal degradation of tetrabromobisphenol A under inert and oxidizing atmospheres. The HBr acted as an excellent brominating agent for PbO and separated Pb as a volatile bromide (79 and 90% in He and He + 5 vol% O2, respectively) from the solid up to 580 °C. For Fe2O3, the amount of vaporized bromide was only 20 and 13% under inert and oxidizing atmospheres, respectively. In inert atmosphere the formed char acted as a reducing agent for converting the remaining oxides into metallic forms. For TBBPA + PbO, about 3% of metallic Pb remained in the residue as most of the oxide vaporized below 970 °C. The unreacted Fe2O3 underwent progressive reduction into metallic Fe (75%), which remained in the residue. In oxidizing atmosphere, the unreacted PbO vaporized completely, while the Fe2O3 remained unchanged in the residue. The organic char decomposed and vaporized as carbon mono- and di-oxides. Simultaneous TG-MS measurements indicated that the presence of PbO and Fe2O3 strongly accelerated TBBPA degradation and enhanced char formation. © 2013 Elsevier B.V. All rights reserved.

  • Concept of EAF dust treatment using waste plastics containing brominated flame retardants

    Mariusz Grabda, Sylwia Oleszek-Kudlak, Etsuro Shibata, Takashi Nakamura

    European Metallurgical Conference, EMC 2013     293 - 302  2013  [Refereed]

    　View Summary

    Tetrabromobisphenol A (TBBPA) is the largest volume brominated flame retardant (BFR) in production today, used in more than 70 % of the world's electronic and electric (E&E) appliances as well as in many plastics, textiles and so forth. There is constant growth in the production of such products and they become obsolete quickly, this generates huge amounts of BFR-containing wastes and causes significant problems for their safe disposal and recycling. Due to the presence of significant amounts of leachable heavy metals, EAF dusts (EAFD) are classified as hazardous wastes. On the other hand the EAF dust contains up to 35 % of Zn, and is considered to be a valuable secondary raw material in the production of zinc. Numerous zinc recovery processes have been developed, many of them, however, were not commercialized because of metallurgical and economical inefficiencies. Few pyrometallurgical processes like Waelz rotary kiln process have achieved commercial success. Its main disadvantage, however, is high energy consumption (Waelz process requires temperatures of 1200-1300 °C). We proposed another alternative method for pyrometallurgical recycling of EAF dust using plastic waste containing BFRs such as TBBPA. It easily decomposes during thermal processing generating large amounts of gaseous HBr that can acts as a brominating agent for the bromination-evaporation of zinc and lead present in the dust. A new concept of EAF dust treatment process is proposed using waste plastics containing BFRs and merits and demerits are discussed with a review of EAF dust treatments in the present paper.

It was found, that the HBr is an excellent brominating agent for ZnO and separates zinc as a volatile bromide (50 and 70% in He and He + 5 vol% O 2, respectively) from the solid residue. In inert atmosphere the formed char plays an important role as reduction agent for remaining ZnO into metallic Zn, which vaporizes completely from the residue above 890 °C. In presence of oxygen, the char is oxidized into CO and CO 2 and un-reacted ZnO remains. Bromination efficiency from thermal treatment of SbBr 3 + ZnO in He is about 14% only. Such low efficiency may results from highly volatile SbBr 3 sublimating from the mixture above 100 °C and its high ability to form thermally stable oxybromide compound (Sb 8O 11Br 2). Simultaneous TG-MS measurements indicate that the presence of ZnO strongly influences the TBBPA degradation pathway and causes enhancement of char formation. Catalyzing effect of ZnO on evaporation of SbBr 3 was also observed. © 2011 Elsevier B.V. All rights reserved.

  • Alternative method for pyrometallurgical recycling of EAF dust using plastic waste containing tetrabromobisphenol A

    S. Oleszek-Kudlak, M. Grabda, E. Shibata, Takashi Nakamura

    High Temperature Materials and Processes   30 ( 4 ) 359 - 366  2011.08  [Refereed]

    　View Summary

    Tetrabromobisphenol A (TBBPA) is the largest volume brominated flame retardant (BFR) in production today, used in more than 70% of the world's electronic and electric (E&E) appliances as well as in many plastics, textiles and so forth. There is constant growth in the production of such products and they become obsolete quickly, this generates huge amounts of BFR-containing wastes and causes significant problems for their safe disposal and recycling. The most common way to use them is in thermal processing. TBBPA easily decomposes during this process, generating significant amounts of gaseous HBr. The HBr is present mostly in the flue gas and can act as a bromination agent for selective bromination-evaporation of heavy metals present in co-combusted metallurgical dusts, like zinc and lead-rich electric arc furnace (EAF) dust. EAF dust, though classified by various government regulatory agencies as hazardous waste, is considered a valuable secondary raw material in the production of zinc. The worldwide generation of EAF dust represents a possible recovery of approximately 1.4 million tons of zinc. Thus the co-combustion of the mixed wastes can be chance for simultaneous recovery of both, energy from waste plastics and inorganic fractions from the dust, while the separated iron oxide-rich residues can be used as iron-making and steelmaking resources. In this study, a laboratory-scale furnace was used to investigate (1) the reactivity of zinc with the product of the thermal decomposition of TBBPA, and effect of (2) temperature on the efficiency of the bromination and vaporization processes.

  • Vaporization of zinc during thermal treatment of ZnO with tetrabromobisphenol A (TBBPA)

    Mariusz Grabda, Sylwia Oleszek-Kudlak, Etsuro Shibata, Takashi Nakamura

    Journal of Hazardous Materials   187 ( 1-3 ) 473 - 479  2011.03  [Refereed]

    　View Summary

    In the present work we investigate the vaporization of zinc or its compounds during thermal treatment of ZnO with tetrabromobisphenol A. Samples of 2g of ZnO:TBBPA (3.34:1) were isothermally heated in a laboratory-scale furnace at temperatures from 490°C to 950°C, and the solid, condensed and gaseous products formed were analyzed by X-ray diffraction analysis, electron probe microanalysis, inductively coupled plasma analysis, ion chromatography, and gas chromatography coupled with mass spectrometry. The results obtained indicate that the vaporization of ZnBr2 formed strongly depends on heating time and temperature, yet is restrained by char, if formed with sufficient yield (above 15wt%). Starting from 850°C, this char commences carbothermic reduction of any remaining ZnO, which from then begins to evaporate as zinc metal vapor. Volatilization of zinc is completed at 950°C. The presence of 5vol.% of oxygen has no significant effect on the vaporization of formed ZnBr2, the carbothermic reduction or the volatilization of metallic zinc. Strongly oxidizing conditions (20vol.% of oxygen), however, boost the oxidation of char and thus the vaporization of ZnBr2, but prevent carbothermic reduction of any un-reacted ZnO by depleting this char. © 2011 Elsevier B.V.

  • Studies on bromination and evaporation of antimony oxide during thermal treatment of tetrabromobisphenol A (TBBPA)

    Journal of Analytical and Applied Pyrolysis   88 ( 1 ) 14 - 21  2010.05  [Refereed]

    　View Summary

    In this paper the bromination reaction between antimony oxide (Sb2O3) and hydrobromic acid, originating from the thermal decomposition of tetrabromobisphenol A (TBBPA), under inert and oxidative atmospheres was investigated using differential scanning calorimetry (DSC) analysis and a laboratory-scale furnace. The results indicate that the bromination follows the decomposition of the TBBPA and takes place below 340 °C in the furnace and around 280 °C during DSC analysis. During thermal treatment of a mixture of TBBPA and Sb2O3 (2.82:1, w/w), it was observed that volatilization of the SbBr3 began immediately after its formation occurred at about 340 °C. The maximum amount of antimony converted into SbBr3 (above 60%) was obtained from runs conducted at temperatures between 440 and 650 °C. The main intermediate products found in the solid residue were Sb4O5Br2 and Sb8O11Br2, which then decompose to more stable compounds such as Sb2O3 at temperatures above 440 °C. Finally, when a temperature of 650 °C is reached, Sb2O3 undergoes a carbothermic reduction into metallic antimony. Additional experiments conducted at selected temperatures under an oxidative atmosphere (He + 5%O2) indicated that the presence of oxygen has only a small influence on the bromination reaction, however, these conditions may enhance the decomposition of TBBPA at 340 °C, which may result in enhanced evaporation of the formed SbBr3 at 340 °C. © 2010 Elsevier B.V.

    　View Summary

    Our prior research indicates that hydrogen bromide (HBr) evolved during thermal decomposition of tetrabromobisphenol A (TBBPA) can be utilized as a reagent for selective bromination and evaporation of zinc oxide. The present work investigated dependency of the bromination reaction on time at selected temperatures using a laboratory-scale furnace. The formed solid, condensed, and gaseous products were analyzed by X-ray diffraction analysis, electron probe microanalysis, inductively coupled plasma analysis, ion chromatography, and gas chromatography coupled with mass spectrometry. Results indicate that the bromination rate is strongly dependent on heating time. This dependency is a direct consequence of progress in the decomposition of TBBPA, which provides inorganic bromine suitable for the reaction. The bromination rate increases with time until the bromine source is depleted. The process is shorter at higher applied temperatures and appears instantaneous at 310°C and above. However, the maximum bromination yield is independent of the applied conditions and ranges from 64 to 70%. Additionally, the influence of oxidizing conditions on the bromination reaction and the effect of ZnO on decomposition of TBBPA were investigated in this study. © 2009 American Chemical Society.

  • Prediction of vapour pressures of chlorobenzenes and selected polychlorinated biphenyls using the COSMO-RS model

    Katsuhiko Nakajoh, Mariusz Grabda, Sylwia Oleszek-Kudlak, Etsuro Shibata, Frank Eckert, Takashi Nakamura

    Journal of Molecular Structure: THEOCHEM   895 ( 1-3 ) 9 - 17  2009.02  [Refereed]

    　View Summary

    The applicability of the Conductor-like Screening Model for Real Solvents (COSMO-RS) for the prediction of the liquid phase vapour pressure of chlorobenzenes (CBzs) and polychlorinated biphenyls (PCBs) is presented. The liquid phase vapour pressures of 12 CBzs, biphenyl and 26 PCBs, and their enthalpies of vaporization derived from the temperature dependence of the predicted vapour pressure using the Clausius-Clapeyron equation. These predicted values using COSMO-RS method were compared not only with the literature data but also with the empirical vapour pressure data, obtained using the Knudsen effusion method in our previous papers. In general, COSMO-RS method successfully predicts the vapour pressures of CBzs and PCBs over a wide temperature range including room temperature. In particular, a good agreement was observed between the COSMO-RS predicted and experimental vapour pressures of low-chlorinated CBzs and non-ortho PCBs. For PCBs, the errors between the predicted and experimentally measured values were larger for the congeners that have more chlorine substitutions in the ortho-position. The Root Mean Square Errors (RMSEs) of the COSMO-RS predictions for CBzs, and the non-ortho, mono-ortho, di-ortho and tri-ortho congeners of PCBs were in the range of 0.035-0.539, 0.079-0.21, 0.28-0.58, 0.47-0.74 and 0.77-0.87, respectively. © 2008 Elsevier B.V.

    Environmental Science and Technology   43 ( 4 ) 1205 - 1210  2009.02  [Refereed]

    　View Summary

    Thermodynamic considerations indicate that base metal oxides such as ZnO, PbO, Cu2O, etc. should easily react with HBr, the main gaseous product from the thermal decomposition of tetrabromobisphenol A (TBBPA), to form low boiling point metallic bromides suitable for volatile separation. In this work a differential scanning calorimeter and laboratory-scale furnace was used to investigate the scope and conditions for the bromination of ZnO by the thermal decomposition of TBBPA. The formed solid, condensed, and gaseous products were analyzed by X-ray diffraction analysis, electron probe microanalysis, inductively coupled plasma analysis, ion chromatography, and gas chromatography coupled with mass spectrometry. The results obtained in this study indicate that the bromination of ZnO occurred at 272°C (DSC) and above 290 °C (furnace) with an effectiveness of 41, 64, and 81% dependent on the experimental conditions. Volatilization of the formed ZnBr2 began at 340 °C and had a 45% yield at 650 °C. This yield corresponded to 28-36% of the original zinc content in the mixture under the present experimental conditions. © 2009 American Chemical Society.

    　View Summary

    The gas phase thermodynamic properties of 209 polybrominated diphenyl ethers (PBDEs), 209 polybrominated biphenyls (PBBs), 19 polybrominated phenols (PBPs), hexabromocyclododecane (HBCD) and tetrabromobisphenol A (TBBPA), including standard state entropy (S{ring operator}), heat capacity (Cp), enthalpy (Δ Hf{ring operator}) and Gibbs free energy of formation (Δ Gf{ring operator}), were predicted using a combination of quantum mechanical computations performed using the Gaussian 03 program at the B3LYP/6-31G(d) level, and thermodynamic relationships derived from the law of energy conservation. The obtained results showed a strong influence of the bromine substitution pattern on the thermodynamic properties of the compounds. For instance, the thermodynamic stability of all congeners decreases with increasing number of Br atoms, especially if substituted at ortho < meta < para positions. Taking into account differences in the Gibbs free energy of formation, the most and least stable congeners in each isomer group were determined. Application of the obtained results in the thermodynamic analysis of the reported experimental stabilities of the compounds afforded the following conclusions: (i) the order of decreasing stability of the PBDEs calculated in this study is in good agreement with the increasing rate of their photochemical degradation; (ii) the formations of lower brominated polybrominated dibenzofurans (PBDFs) instead of adequate congeners of PBDEs during the photolytic debromination of decabromodiphenyl ether (DeBDE) seemed to be thermodynamically favored; (iii) the debromination of PBDEs does not follow just one thermodynamic path, but is rather multidirectional, leading to a mixture of several congeners, the concentration of which is related to their thermodynamic stability. © 2007 Elsevier B.V.
