摘　　要：甲壳胺是甲壳素脱乙酰基的产物，由于分子中游离氨基的存在，使它对一些金属离子，尤其是过渡金属离子具有较好的螯合能力，因而被作为重金属离子的天然吸附剂和高分子金属催化剂的研究对象［１，２］．目前文献报道的以Ｃｕ（Ⅱ）和Ｐｄ（Ⅱ）的配合物居多，且配合物的制...A series of chitosan Zn(Ⅱ) complexes with n (chitosan) n (Zn(Ⅱ)) =10 05～ 11 0 were synthesized in aqueous acidic solution. The results indicated that the Zn(Ⅱ) content of the complexes prepared in dilute formic acid solution was higher than in other acid solutions: acetic, propionic, benzoic and hydrochloric acids. IR spectrum results showed that Zn(Ⅱ) are coordinated to NH 2, NHCO and OH groups of chitosan molecnle and the final complexes have no definite chemical composition.
