摘　　要：采用β-环糊精和丙烯酸为原料制备了互穿网络聚合物p-β-CD-AA,研究了其对亚甲基蓝的吸附性能,并对其等温吸附模型进行了拟合。结果表明:在亚甲基蓝溶液浓度为20mg/L,pH=7的条件下平衡吸附量最高,温度对吸附亚甲基蓝的影响不大。p-β-CD-AA对亚甲基蓝的吸附符合Freundich模型,属于多分子层吸附。The interpenetrated network polymer p-β-CD-AA was prepared by usingβ-cyclodextrin and acrylic acid as raw materials,and its adsorption performance on methylene blue was studied,and its isothermal adsorption model was fitted.The results show that the balanced adsorption amount is highest under the condition that the concentration of methylene blue solution is 20 mg/L and pH=7,and the temperature has little effect on the adsorption of methylene blue.The adsorption of p-β-CD-AA on methylene blue conforms to the Freundich model and belongs to the multimolecular layer adsorption.
