Thiosemicarbazone and Semicarbazone Chelating Resins and Their Potential Use in Environmental Applications
An effective means for removing harmful metals from the environment has been studied through the use of thiosemicarbazone (TSC) and semicarbazone (SC) chelating resins. The ability to chelate radioactive tracer metals out of aqueous solutions at environmental pH values was observed with these resins. Resin loading data was studied to determine the amount of exchange sites occupied by the ligands. The comparative ability of three different structural backbones on the ligand structures to adsorb radioactive tracer metals was determined by a batch technique at various pH values. Dry-weight distribution, D-w, values were calculated for the chelating resins.
