摘　　要：巯基胺型螯合树脂经烷氧基环硫丙烷和二烷基胺基环硫丙烷改性后。合成了一系列新的螫合树脂．这些树脂与原树脂相比，对贵金属离子的吸附性能有一定的改善．特别是用二烷基胺基环硫丙烷改性后的树脂，效果更为明显．还讨论了树脂结构与吸附性能之间的关系．A series of chelating resins were synthesized by the reactions of mercaptoamine resins with alkoxylepithiopropanes or dialkylaminoepithiopropanes.The adsorption properties for precious metal ions of the new chelating resins,especially modified with dialkylaminoepithiopropanes,were improved in comparison with those of original resins. The relationship between the structures of resins and adsorption properties were discussed as well.
