摘要
本工作用Ｎ，Ｎ－二乙氨基环氧丙烷和Ｎ，Ｎ－二乙氨基环硫丙烷分别与含仲氨基的高分子载体进行反应，合成得到两类分别含羟基和巯基的叔胺型螯合树脂；用静态法测定了树脂对Ａｕ（Ⅲ），Ｐｄ（Ⅱ），Ｐｔ（Ⅳ），Ａｇ（Ⅰ），Ｈｇ（Ⅱ），Ｃｕ（Ⅱ），Ｚｎ（Ⅱ）的吸附特性，结果发现树脂对于贵金属离子有较好的吸附性能。
A series of trialkylamine type chelating resins containing hydroxyl and thiohydroxyl groups were synthesized through reactions of polymers CN with diethylaminomethyloxirane (ON) and diethylaminomethylthiirane (SN) respectively. The adsorption properties of these resins to some metal ions such as Au ( Ⅲ ),Pd( Ⅱ ),Pt(Ⅳ ),Ag( Ⅰ ),Hg( Ⅱ ),Cu( Ⅱ ),Zn( Ⅱ ) were measured by static method. The results indicated that the resins can adsorb some noble metal ions effectively.
