摘　　要：采用缩聚反应，一步法合成了三乙烯四胺（ＴＥＴＡ）型的非模板和以Ｃｕ（Ⅱ）离子为中心模板离子的高分子铜模板络合吸附剂。研究了这类吸附剂在静态条件下对重金属离子Ｃｕ２＋、Ｎｉ２＋、Ｃｏ２＋、Ｚｎ２＋和动态条件下对Ｃｕ２＋、Ｎｉ２＋的吸附选择性。结果表明，钢模板吸附剂比非模板吸附剂对重金属离子的吸附选择性显著提高。A series of complexing polymeric adsorbents which were made of the cross-linked polyamine and cupric(Ⅱ) as the template were directly synthesized through the condensation of epichlorohydrin and triethylene tetramine in an oil disperse system. Characterizanon of the sorption for Cu(Ⅱ), Ni(Ⅱ), Co(Ⅱ) and Zn(Ⅱ) transition-metal ions under the static equilibrium condition and the adsorption selectivities for Cu(Ⅱ) and Ni(Ⅱ) under the kinetic equilibrium condition were studied. The experimental results showed that the adsorption selectivity of the complexing adsorbents containing cupric(Ⅱ) as the template is increased as compared with the non-template.
