中文摘要：

采用溶剂热法,用H3PW6Mo6O（40）对金属有机骨架Zn（BDC）（4,4＇-Bipy）（0.5）进行改性,制备出金属有机骨架复合材料H3PW6Mo6O（40）/Zn（BDC）（4,4＇-Bipy）（0.5）。利用IR、XRD、TG、SEM对其结构进行分析。同时,以亚甲基蓝溶液模拟染料废水进行吸附实验,考察了初始p H、温度对吸附容量的影响,探究了其吸附等温线和动力学特征。实验结果表明,H3PW6Mo6O（40）/Zn（BDC）（4,4＇-Bipy）（0.5）对亚甲基蓝有很好的吸附性能,在20℃和pH 2的条件下,吸附量达588.24mg/g,且该吸附符合Langmuir等温吸附模型和拟二级动力学方程,吸附过程自发且放热。

英文摘要：

H3PW6Mo6O（40）/Zn（BDC）（4,4＇-Bipy）（0.5）was synthesized by the solvothermal synthesis method,and the metal organic framework Zn（BDC）（4,4＇-Bipy）（0.5）were modified by H3PW6Mo6O（40）.The structures of the composite were confirmed by IR,XRD,TG,SEM.Meanwhile,methylene blue dye solution is used to simulate waste water and to explore the influences of the adsorption process containing the initial p H,temperature.It＇ s adsorption isotherm and kinetic model were also explored.The results show that H3PW6Mo6O（40）/Zn（BDC）（4,4＇-Bipy）（0.5）has great adsorption capacities for the methylene blue.It＇s maximum adsorption capacity value reached 588.24 mg/g at 20 ℃ and pH 2.The experiment data could be well described by the Langmuir equations and pseudo-second-order kinetic model.The adsorption process of the composites on methylene blue was spontaneous and exothermic.
