Abstract |
Anion removal in water treatment is one of important issues because anion causes damage both human body and environment. Anion exchange resins of polymer base are widely used; however, anion exchange resins have disadvantages such as environmental problems of secondary waste, low performance by interference phenomena, and high cost.
To overcome the disadvantages mentioned above, in this study, we developed an anion adsorption material for water treatment using calcium bentonite, an environmental friendly natural mineral, complexed with quaternary alkyl ammonium. In order to confirm the anion removal performance of the material, series of appropriate experiments to estimate adsorption equilibrium were carried out, and excellent performance of perchlorate removal was confirmed thermodynamically. Furthermore, adsorption properties were investigated with analysis equipments (i.e. SEM, EA, TGA, XRD, and FTIR) and computational approaches (i.e. molecular and adsorption modelling). By using calcium bentonite, which is an abundant resource, we suggested novel approach that how the disadvantages of the anion exchange resins used in conventional water treatment can be overcome. It is expected that the developed material could be applied to the water treatment process to be efficient.
