摘　　要：含有重金属离子和有机化合物分子的污水具有产生量大、难处理等特点,对生态环境和人类健康均有潜在危害。环糊精聚合物(CDPs)既保留了环糊精自身的空腔及空腔外多羟基结构特征,同时也结合了聚合物的结构稳定性、基团多样性等优势,在污染物处理方面得到了广泛应用与关注。本文详细介绍了CDPs作为吸附剂的两种经典制备方法——交联法和固载法,阐述了其近年来在吸附染料分子、重金属离子、酚类物质以及药物分子方面的应用,分析了其作为吸附剂对不同污染物的吸附机理,并对CDPs研究与应用的发展趋势进行展望。The wastewater containing heavy metal ions and organic compounds has the characteristics of large production and difficult treatment,which is potentially harmful to the ecological environment and human health.Cyclodextrin polymers(CDPs)not only retain the characteristics of the cavity and the polyhydroxyl structure outside the cavity of cyclodextrin,but also combine the advantages of structural stability and group diversity of the polymer,and have been widely used and concerned in the treatment of pollutants.In this paper,two classical preparation methods for CDPs as adsorbent,crosslinking method and solid loading method,are introduced in detail,and their applications in adsorbing dye molecules,heavy metal ions,phenols and drug molecules in recent years are described.The adsorption mechanism of CDPs as adsorbent for different pollutants is analyzed,and the research and application status and development trend of CDPs are prospected.
