【摘要】 合成了-环糊精聚合物,并采用红外光谱、元素分析及BET吸附法对聚环糊精进行了表征。从吸附动力学和热力学角度研究了聚环糊精对苯酚的吸附性能,拟合出了Langmuir吸附模型中的各参数。结果表明,聚环糊精对苯酚的吸附容量可达12mg/g以上,且吸附能力主要来自聚环糊精对苯酚的包合作用。更多还原

【Abstract】 cyclodextrin polymer (CDP) was prepared and characterized by FTIR, element analysis and BET. The adsorption property of CDP for phenol from aqueous solution including adsorption kinetics, adsorption equilibrium and the effect of pH on adsorption capacity wereinvestigated preliminarily, and Langmuir parameters were obtained by experimental dataapproximation.. The adsorption capacity of CDP for phenol reached 12mg/g or more , and its adsorption ability was mainly due to its inclusion effect for phenol rather than only physical adsorption.更多还原
