【Abstract】 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.更多还原
