摘    要:<正> Three chelating resins were prepared by re-acting poly (β-chloroethyl glycidyl ether) with benzidine, o-tolidine and o-dianisidine respectively, and their structureswere confirmed by IR spectra and elementary analyses. Theadsorption properties of the resins for Au (Ⅲ), Pd (Ⅱ). Pt(Ⅳ),Hg(Ⅱ) .Cu(Ⅱ),Pb(Ⅱ) and Zn(Ⅱ) were also investi-gated. The results show that the resin incorporating o-diani-sidine exhibits high affinity for Au (Ⅲ) within a broad rangeof hydrochloric acid .and selectively sorbs Au (Ⅲ) in the coexistance of Cu(Ⅱ), Zn(Ⅱ) and Mg (Ⅱ). Desorption of Au(Ⅲ),Pd (Ⅱ) and Pt (Ⅳ) sorbed proceeded quantitatively us-ing 0. 1 mol/l hydrochloric acid containing 2%-10% thioureaas desorbents.
