| 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^＋, Hg^2＋, Au^3＋ and Pd^2＋, and the presence of spacer arm can enhance adsorption ability due to increase the hydrophilicity of the chelating resins.

| Abstract: | 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 co ntaining 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. |
