Abstract: This study investigated the performance of two anion exchange resins and also synthesized and evaluated the performance of a hybrid material consisting of a strong base anion exchange resin dispersed with FeS (iron sulphide) nanoparticles for the removal of hexavalent chromium, Cr(VI). The synthesis of the hybrid was carried out by using an in situ process, where the strong base anion exchange resin serves as a nanoreac-tor and provides a confined medium for synthesis. They stabilize and isolate the synthesized nanoparticles preventing their aggregation. Equilibrium batch studies, adsorption isotherm and column studies were performed to determine the maximum uptake capacity for Cr(VI). Comparison of a fixed bed column run between the hybrid material and parent resin confirmed that the Cr(VI) was selectively removed and the hybrid showed higher capacity. The wide availability of resin and low-cost chemicals for synthesis and regeneration will make hybrid material an attractive option for the removal of Cr(VI) from contaminated water. ¬© 2018 Taylor & Francis Group, London.
