摘　　要：Two kinds of new chelating resins containing heterocyclic functional group(1-amino-5-methylthio-1,3,4-thia-dizole) were synthesized from macroporous chloromethylated polystyrene.Their structures were characfterized by elemental analysisand infrared spectra.Their adsorption properties for Cu2 +,Pb2 +,Ni2 +,Zn2 +,Ag+and Hg2 +had been studied.The results showthatthe newly synthesized resins have highly selective for Ag+and Hg2 +and the resin has no affinity for Cu2 +、Pb2 +and Ni2 +.The in-troduction of hydrophilic polyvinyl alcohol spacer arm can increase the adsorption capacity and the length of spacer arm has effecton the adsorption capacities.Two kinds of new chelating resins containing heterocyclic functional group（ 1 - amino -5 - methylthio - 1,3,4 - thia- dizole） were synthesized from macroporous chloromcthylated polystyrene. Their structures were characfierized by elemental analysis and infrared spectra. Their adsorption properties for Cu^2＋ ,Pb^2＋ ,Ni^2＋ ,Zn^2＋ ,Ag^＋ and Hg^2＋ had been studied. The results show that the newly synthesized resins have highly selective for Ag^＋ and Hg^2＋ and the resin has no affinity for Cu^2＋ .Pb^2＋ and Ni^2＋. The introduction of hydrophihc polyvinyl alcohol spacer arm can increase the adsorption capacity and the length of spacer arm has effect on the adsorption capacities.
