摘要:
A series of new chelating resins with incorporating heterocyclic functional groups: pyridine, thiadizole, benzothizole into macroporous chloromethylated polystyrene were synthesized via hydrophilic spacer arm of polyethylene glycol containing sulfur. These chelating resins were found to show high adsorption capacities for Ag+, Hg2+, Au3+ and Pd2+, and the presence of spacer arm can enhance adsorption ability due to increase the hydrophilicity of the chelating resins.
