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.
