摘　　要：以锌离子为模板，合成了戊二醛交联壳聚糖树脂，通过对过渡金属离子吸附性能的研究．结果表明，该法合成的树脂对Zn（Ⅱ）离子具有较强的“记忆”能力，且对同族的Cd（Ⅱ）Hg（Ⅱ）也有较高吸附量．在酸性下条件再生不会发生软化和溶解，重复使用性能良好．Using Zn(Ⅱ) ion as template, a cross-linked chitosan resin was synthesized by reacting chitosan with the glutaraldehyde. The adsorption capacities of the template resin for transition metal ions were studied. The results indicated that the resin has considerable adsorption capacity for Zn(Ⅱ), Cd(Ⅱ), Hg(Ⅱ).The resin was stable under acidic condition and could be reused.
