摘　　要：壳聚糖对金属离子有良好的配位作用。经化学改性之后,壳聚糖衍生物-羧甲基壳聚糖对金属离子的配位能力进一步增强。该文主要就壳聚糖和羧甲基壳聚糖与不同金属离子的配位机制、配位条件以及配合物的物化性质做一综述。Chitosan has well ability to bind metal ions. After chemical modifications, carboxymethyl chitosan has better ability to bind metal ions than chitosan. Complexation mechanisms of chitosan and carboxymethyl chitosan complex with various metal ions, as well as the complexation condition and the physicochemical properties were reviewed.
