The primary goals of the project are to synthesize and develop a hybrid inorganic ion exchanger and investigate its selective heavy-metal-removal properties. The proposed exchanger will not require any environmentally regulated chemical for its synthesis. Laboratory studies will be carried out to optimize the synthesis process and characterize the exchanger pertaining to its various physico-chemical properties. One of the major goals of the project is to benchmark the heavy-metal-removal performance of this new exchanger in comparison with commercial chelating exchangers. The regenerability of this new exchanger and its ability for multiple-cycle operation will be looked into. Attempts will also be made to assess the role of heterogeneity on the underlying metals sorption mechanism.
