Bifunctional resin-supported nanosized zero-valent iron (N-S-ZVI) composite was developed by combining the oxidation properties of nZVI/O2 with adsorption features of iron oxides and anion-exchange resin N-S. In batch culture experiments, N-S and the N-S-ZVI composite were examined for As(III) and As(V). The results reveal that ZVI in the composite played a key role in enhancing As(III) removal. The N-S-ZVI composites could oxidize more toxic As(III) to less toxic As(V) with high efficiency… CONTINUE READING
