摘　　要：重金属离子对水体质量和生态环境具有显著影响,在自然界中重金属离子不能被天然降解,对人类及动物都构成了严重的威胁,因此从水中去除重金属离子是不可忽视的问题.现阶段吸附法因其简单方便而被广泛使用,其中壳聚糖已经成为比较常用的重金属离子吸附剂.综述了硅藻土、膨润土、高岭土、蒙脱土、凹凸棒与壳聚糖合成的复合材料对重金属离子的吸附性能,以及存在的问题,并对未来的发展进行了展望.There is a significant impact on water quality and ecological environment of heavy metal ions.In nature,heavy metal ions cannot be degraded naturally and pose a serious threat to human beings and animals.Therefore,the removal of heavy metal ions from water is a problem that cannot be ignored.At present,adsorption method is widely used because of its simplicity and convenience,among which chitosan has become a more commonly used heavy metal ions adsorbent.The adsorption of heavy metal ions on chitosan modified composite materials by clay minerals such as diatomite,bentonite,kaolin,montmorillonite,attapulgite,as well as the existing problems are reviewed,and the future development is prospected.
