  • Experimental study and surface complexation modeling of fluoride removal by magnesium hydroxide in adsorption and coprecipitation processes

    Kosuke Tsuchiya, Shigeshi Fuchida, Chiharu Tokoro

    Journal of Environmental Chemical Engineering   8 ( 6 )  2020.12  [Refereed]

     View Summary

    © 2020 Elsevier Ltd. High contaminated levels of fluoride (F) in groundwater and drinking water are of significant concern for human health in many countries. This study examined adsorption and coprecipitation for effective F- removal from high F-containing water using inexpensive magnesium hydroxide, Mg(OH)2. Fluoride solutions were reacted with Mg2+-or Mg(OH)2-containing solution at different F/Mg molar ratios of 0.05-2, and the F- removal performance and mechanisms were investigated in both processes. As a result, the residual amount of F- in the solution decreased with an increase in Mg2+ concentrations for both processes, and the sorption isotherms followed the Langmuir type. Mg(OH)2 was precipitated only after F- removal, which suggests that adsorption to Mg(OH)2 was the main removal mechanism in both processes. However, the saturated adsorption capacity in the coprecipitation process was two times higher than that in the adsorption process. The chemical equilibrium calculation results implied that the surface complexation of MgF° and MgOH2F° was the dominant mechanism in the adsorption process whereas multiple complexations of Mg-MgF3° and Mg-MgF4- occurred in the coprecipitation process. This complex formation improves F- removal; hence, coprecipitation with Mg(OH)2 exhibited better potential as an efficient process for the treatment of industrial wastewater that contains F-.

  • Insight into the Mechanism of Arsenic(III/V) Uptake on Mesoporous Zerovalent Iron-Magnetite Nanocomposites: Adsorption and Microscopic Studies.

     View Summary

    Mesoporous zerovalent iron-magnetite nanocomposites (ZVI-MNCs) were developed to circumvent the limitations of magnetite, such as its susceptibility to phase transition in air-water interfaces. High-resolution transmission electron microscopy images revealed the presence of Fe0 and Fe3O4 in the as-prepared adsorbent. High-resolution X-ray photoelectron spectroscopy (HR-XPS) Fe 2p deconvoluted spectra showed that electron transfer between Fe0 and Fe3O4 controlled the magnetite transformation. The isotherm equilibrium data for As(III) and As(V) are described by the Sips model, which suggests single- and multilayer formation onto a heterogeneous surface with different binding sites, whereas adsorption is controlled by a pseudo-second-order kinetic model, which indicates chemisorption. The maximum sorption capacities (qm) for As(III) and As(V) are 632.6 and 1000 μmol g-1, respectively, which are larger than the qm of similar adsorbents. The greater qm for As(V) is attributed to a higher multilayer formation and a stronger bonding force compared with As(III). The arsenic uptake capacity showed that the as-prepared adsorbent was effective over a wide pH range, and an optimal uptake capacity was recorded between pH 5.0 and 9.0 for As(III) and 3.0 and 7.0 for As(V). The adsorbent exhibited a remarkable regeneration performance for As(III) and As(V) uptake. Several microscopic analytical tools, including Fourier transform infrared spectroscopy, HR-XPS, and X-ray absorption near-edge structure together with zeta potential, confirmed that the binding mode of As(III) and As(V) on ZVI-MNCs was predominantly inner-sphere coordination. Partial redox transformation occurred for As(III) and As(V) on nearly 10 nm of the adsorbent, which indicates that a surface redox mechanism contributed partially to arsenic uptake on the near surface of the ZVI-MNCs. Extended X-ray absorption fine structure spectral analysis proposed that a corner-sharing monodentate mononuclear (1V) complex occurred for As(III) with a small portion of a corner-sharing bidentate binuclear (2C) complex, whereas As(V) formed a corner-sharing bidentate binuclear (2C) complex with octahedral Fe bonding.
