Abstract

Modified carboxymethyl cellulose with β-cyclodextrin (CMC-β-CDP) was prepared and the sorption properties of CMC-β-CDP towards xylenol orange (XO) were investigated. Studies concerning the effects of contact time, sorption temperature and initial XO concentration were discussed. Results of batch experiments showed that CMC-β-CDP exhibited some sorption capacities towards XO. The isotherm fitted Freundlich model for the sorption of XO on CMC-β-CDP. The sorption capacities of CMC-β-CDP, β-cyclodextrin polymer (β-CDP) and carboxymethyl cellulose (CMC) towards XO in aqueous solutions were investigated. Results of contrast experiments showed that the sorption capacity of CMC-β-CDP for XO was higher than that of CMC and β-CDP.

改性羧甲基纤维素对二甲酚橙的吸附

制备了β-环糊精改性羧甲基纤维素(CMC-β-CDP)，并研究了CMC-β-CDP对二甲酚橙(XO)的吸附性能。讨论了接触时间、吸附温度和初始XO浓度对吸附效果的影响。批量实验结果表明，CMC-β-CDP对XO有一定的吸附能力。等温线拟合了XO在CMC-β-CDP上吸附的Freundlich模型。研究了CMC-β-CDP、β-环糊精聚合物(β-CDP)和羧甲基纤维素(CMC)在水溶液中对XO的吸附性能。对比实验结果表明，CMC-β-CDP对XO的吸附量高于CMC和β-CDP。
