系统地综述了绿色环保的壳聚糖类吸附材料的制备方法及其在废水处理中的应用。主要梳理和总结了壳聚糖类吸附剂对重金属离子的吸附机理、制备吸附剂的方法以及在处理重金属Cu²⁺、Pb²⁺、Cr²⁺等离子方面的应用效果，并以此为基础对壳聚糖类吸附剂的研究现状及其研究方向进行了总结和展望。

Based on a large number of literature research,the preparation methods for environmental friendly chitosan-derived adsorption materials are systematically reviewed and the application of chitosan-derived adsorption materials in wastewater treatment are also described.This review also involves in the adsorption mechanism of chitosan-series adsorbents to heavy metal ions,the preparation method of the adsorbents and the application effect of the adsorbents in the treatment of Cu²⁺,Pb²⁺,CR²⁺ and other heavy metal ions.Based on this,the research status and direction about chitosan-based adsorbent are summarized and prospected in order to provide some theoretical references for the coming research.
