摘　　要：本文综述了近年来壳聚糖在金属离子吸附方面的研究进展,主要介绍了壳聚糖的改性方法和各种改性壳聚糖对金属离子的吸附情况。Chitosan are naturally abundant biopolymers which are of interest to research concerning the sorption of metal ions since the amine and hydroxyl groups on their chemical structures act as chelation sites for metal ions. The recent progress in absorption for metal ions based the derivates of chitosan was summarized in this paper. The ways of modification and absorption effect of modified chitosan for metal ions were also mainly introduced.
