摘　　要：作为新型的吸附材料,凹凸棒石有可再生和低能耗的优良特性,被广泛应用于污水处理方面;壳聚糖由于其可生物降解、抗菌、亲水、可再生、生物相容性和环保等优势被广泛应用于重金属离子、含酚类废水、印染废水等废水处理领域中。而将两种材料复合,则对重金属离子以及难降解有机污染物展现出更加优异的吸附能力。通过综述该复合材料的研究进展,了解到该复合材料对重金属离子以及难降解有机废水的吸附性能对比单一材料都有所提升。最后分析了该复合材料目前研究的局限性并对将来的研究方向进行了展望。As a new type of adsorption material,attapulgite has excellent characteristics of renewable and low energy consumption,and is widely used in wastewater treatment.Chitosan is widely applied in the treatment of heavy metal ion,phenolic wastewater,printing and dyeing wastewater because of its biodegradable,antibacterial,hydrophilic,renewable,biocompatible and environmental protection advantages.When the two materials are combined,they show better adsorption capacity for heavy metal ions and difficult to degrade organic pollutants.By reviewing the research progress of this composite material,it was known that the adsorption performance of this composite material for heavy metal ions and difficult to degrade organic wastewater was improved compared with that of a single material.Finally,the limitations of the current research on the composites were analyzed and the future research direction was prospected.
