摘要：

通过对水中含有微量氯苯的吸附特性研究，考察β-环糊精交联聚合物吸附氯苯的动力学、热力学及连续运行条件下的稳定性和再生性能。实验结果表明：β-环糊精交联聚合物吸附氯苯的过程符合准二级动力学模型，即化学吸附是吸附过程的控制步骤；β-环糊精交联聚合物上的等温吸附符合Langmuir吸附等温模型。在15、 25、35 ℃时最大吸附量分别为23.36、 28.17、27.85 mg/g；动态模拟实验中，当氯苯质量浓度为10 mg/L时，氯苯的去除率大于80%。乙醇作为溶剂可以使吸附饱和的β-环糊精交联聚合物再生。

Abstract:

Batch adsorption experiments were carried out for the kinetics and equilibrium of Chlorobenzene(CB) in aqueous solutions using a β-cyclodextrin cross-linked polymer(β-CDP) as adsorbent，and the regeneration capacity of β-CDP. The removal efficiency and the stability of β-CDP treating Chlorobenzene under continuous operating conditions were simulated. Adsorption data were fitted using the pseudo-first-order, pseudo-second-order kinetic equations, Langmuir and Freundlich model. It was found that the adsorption kinetics followed a pseudo-second-order model for CB concentration range studied in the present work, suggesting that the rate-limiting step may be chemisorption. The adsorption data fit the Langmuir isotherm model and the maximum adsorption capacity of CB at 15, 25, 35℃ were 23.36, 28.17, 27.85 mg/g, respectively.
