摘　　要：用二异氰酸酯交联β-环糊精合成了β-环糊精聚合物,并通过红外光谱和测定固含量和溶胀率来进行分析.分别在不同投料比得到的聚合物、不同吸附温度和不同被吸附溶质浓度情况下,研究了聚环糊精对对硝基苯酚的吸附性能和解吸性能.结果发现,聚环糊精的吸附和解吸性能都很强,可作为循环吸附材料.β-cyclodextrin polymer （β-CDP） is prepared by crosslinking β-cyclodextrin with diisocyanate and analyzed by using FTIR and measuring the solid content and swelling ratio. The adsorption and desorption properties of β-CDP for p-nitrophenol from aqueous solution are investigated under different situations, including β- CDPs prepared with different reactant ratios, different adsorption temperatures and adsorption concentrations. The result show that the adsorption and desorption capacities of β-CDP are so strong that it can be used as a kind of recyclable sorbents.
