摘　　要：采用原位浸渍法合成了Cu-BTC/PUS复合材料,利用XRD,FTIR,XPS,ICP-OES等方法分析了复合材料结构性质及其吸附Ce^3+的性能。实验结果表明,复合材料对Ce^3+的吸附过程同时存在离子交换反应和络合配位反应,吸附过程符合Langmuir方程和准二级动力学模型。在pH=6、25℃和溶液初始浓度为600 mg/L时,Cu-BTC/PUS复合材料对Ce^3+的最大吸附量为177 mg/g。Cu-BTC/PUS composites were synthesized by the in-situ impregnation method.The structural properties of composites and their adsorption properties of Ce^3+ were analyzed by XRD,FTIR,XPS,and ICP-OES.The result shows that there are both ion exchange reaction and complexation coordination reaction in the adsorption process of Ce^3+.The adsorption performance is in conformity with the Langmuir isotherm model and the pseudo-second-order dynamic model.The Cu-BTC/PUS composites show the highest adsorption capacity of 177 mg/g for Ce^3+at pH 6,25℃and initial concentration of solution 600 mg/L.
