摘　　要：采用溶剂热法将H_(6)P_(2)Mo_(18)O_(62)包覆在UiO-66金属有机骨架周围,制备H_(6)P_(2)Mo_(18)O_(62)/UiO-66复合材料.通过SEM、PXRD、FT-IR等手段对制备的样品进行表征,确定了H_(6)P_(2)Mo_(18)O_(62)与UiO-66的成功复合.采用MB为目标染料探究吸附剂H_(6)P_(2)Mo_(18)O_(62)/UiO-66的吸附性能,结果显示该吸附剂对阳离子染料具有高选择性吸附.吸附机理实验证明,复合材料H_(6)P_(2)Mo_(18)O_(62)/UiO-66对MB吸附过程切合Langmuir等温吸附模型以及拟二级动力学模型,属于自发的吸热反应.The H_(6)P_(2)Mo_(18)O_(62)was wrapped around the UiO-66 metal organic framework by solvothermal method to prepare H_(6)P_(2)Mo_(18)O_(62)/UiO-66 composite material.The prepared samples were characterized by means of SEM,PXRD,FT-IR,etc.,and the successful combination of H_(6)P_(2)Mo_(18)O_(62)and UiO-66 was determined.Using MB as the target dye to explore the adsorption performance of the adsorbent H_(6)P_(2)Mo_(18)O_(62)/UiO-66,the results show that the adsorbent has a highly selective adsorption of cationic dyes.The adsorption mechanism experiment proves that the composite material H_(6)P_(2)Mo_(18)O_(62)/UiO-66 fits the Langmuir isotherm adsorption model and pseudo-second-order kinetic model for the MB adsorption process,which belongs to the spontaneous endothermic reaction.
