摘　　要：By the suspended condensation reaction of poly(choloromethylthiirane)with o-tolidine and o- dianisidine respectively, two newmicrobeads chelating resins were synthesized by usingγ-Fe_2O_3 asmagnetic core. Their adsorption properties for Hg(Ⅱ), Cu(Ⅱ), Zn(Ⅱ), Pb(Ⅱ), Au(Ⅲ), Pd(Ⅱ), Pt (Ⅳ)and Ag(Ⅰ)were investigated. Themicrobeads posses excellent adsorbability for Hg(Ⅱ) and noble metalions, and predominantly adsorbed Pd(Ⅱ)or Hg(Ⅱ)in the coexistence ofCu(Ⅱ), Zn(Ⅱ)and Mg(Ⅱ).By the suspended condensation reaction of poly(choloromethylthiirane)with o-tolidine and o- dianisidine respectively, two newmicrobeads chelating resins were synthesized by usingγ-Fe_2O_3 asmagnetic core.
