摘　　要：通过β-环糊精与六亚甲基二异氰酸酯反应得到了非水溶性环糊精交联共聚物,研究了15～60℃下,β-环糊精聚合物对浓度为20～50 mg/L苯酚溶液的吸附过程,分别采用5类吸附动力学方程、4类平衡吸附等温线方程对实验数据进行了拟合,通过7类误差分析方程对拟合结果进行了相互比较。结果显示,二阶Lagergren Ⅲ方程和Freundlich Ⅰ方程分别是最佳的吸附动力学方程和平衡吸附等温线方程,适用于描述β-环糊精聚合物对苯酚的吸附过程。Water-insoluble cyclodextrin crosslinked copolymer was prepared by reacting β-cyclodextrin with hexamethylene diisocyanate.Adsorption behaviors of β-cyclodextrin polymer to phenol of 20~50 mg/L were studied at the temperatures from 15℃ to 60℃.The experimental data were fitted by five adsorption kinetic model and four isotherm model,respectively,and fitting results were evaluated by seven error analysis equations.The results indicated that the best adsorption kinetic model was second order Lagergren III and the best adsorption isotherm model was Freundlich I,which were suitable for describing the adsorption process of phenol by β-cyclodextrin polymer.
