摘　　要：采用水热法合成磷钼酸铵/1,3,5-苯三甲酸铜(II)杂化化合物(AMP/Cu-BTC),通过红外光谱、X射线衍射和电子显微镜扫描等手段对材料进行了表征,并研究了AMP/Cu-BTC对水溶液中Cs+的吸附性能。结果表明,晶体材料AMP/Cu-BTC对Cs+具有一定的吸附功能,平衡吸附量为29.01 mg/g;符合准二阶动力学方程,其qe=31.348 mg/g,R2=0.998 9;等温线符合Langmuir吸附等温式。AMP/Cu-BTC hybrid materials was prepared by hydrothermal synthesis method.The resultant material was characterized by infrared(IR) spectroscopy,powder X-ray diffraction(XRD),and scanning electron microscope(SEM).The Cs+ adsorption by aqueous solution by AMP/Cu-BTC was investigated,the maximum adsorption capacity was up to 29.01 mg/g.The adsorption process attributes to pseudo second-order kinetics model,qe=31.348 mg/g and the equilibrium isotherm for Cs+ uptake corresponds closely to the Langmuir model.
