摘　　要：工业的快速发展使水体污染问题日趋严重且威胁人类健康。因此,针对水体污染物的去除治理迫在眉睫。高性能吸附剂的成功制备使吸附技术成为最具应用前景的技术之一。β-环糊精聚合物既保留了β-环糊精结构中具有吸附位点的羟基基团和空腔结构,又解决了β-环糊精单体在水体中易溶解及稳定性较差的问题,在去除水体污染物方面备受关注。然而,β-环糊精聚合物会因不同的制备方法而具有不同的吸附性能。该文详细阐述了交联型、星型、线型、固载型4种β-环糊精聚合物的结构特点及制备方法,综述了近年来对水体污染物中重金属、染料、内分泌干扰物等污染物的吸附机理和应用,并对其未来发展进行了展望。The rapid industrial development leads to severe water pollution,which poses threat to human health.Therefore,the removal and treatment of water pollutants is of urgency.The successful preparation of high-performance adsorbents has made adsorption one of the most promising technologies for water pollutant treatment.β-Cyclodextrin polymers retain the hydroxyl group and cavity structure with adsorption sites in cyclodextrin structure,while solve the problems of easy dissolution and poor stability ofβ-cyclodextrin monomer in water,attracting much attention in the removal of aqueous pollutants.However,the adsorption performance ofβ-cyclodextrin polymers was determined by their preparation methods.Herein,the structural characteristics and preparation methods of four kinds ofβ-cyclodextrin polymers(crosslinked,star,linear and supported)were described in detail,followed by discussion on the mechanism and application in adsorption of heavy metals,dyes,endocrine disruptors and so on in water pollutants in recent years.Finally,the future development ofβ-cyclodextrin polymers was also prospected.
