摘　　要：The traditional techniques for treating wastewater contaminated by heavy metals mostly involve chemical precipitation,solvent extraction and adsorption,ion-exchange,chemical precipitation,and membrane separation.The main shortcomings of traditional procedures are low economic efficiency,lack of environmental friendliness,and poor selectivity.Cyclodextrins are artificial compounds that resemble cages.Through host-guest interaction,pollutants can be adsorbed by its stable inner hydrophobic chamber and exterior hydrophilic surface.It is not only inexpensive and environmentally friendly,but also quite selective.The synthesis and application of materials were reviewed,as well as the primary influencing factors,and the reaction principle of cyclodextrin adsorbent materials for better separation of heavy metal ions.And the future trend of discovery was described.重金属污染废水治理的传统方法主要有化学沉淀法、溶剂萃取法、离子交换法、电化学法和膜分离法等。传统方法存在的问题在于选择性差,经济效益低且环境不友好。环糊精是一种人工合成的笼状分子,具有稳定的内疏水腔和外亲水表面,可以通过主客体作用将污染物封装在其内部,具有选择性强、绿色环保且成本较低的优势。主要综述了环糊精吸附材料强化分离重金属离子的反应原理、材料的合成与应用及其主要影响因素,并对未来发展趋势进行了展望。
