采用静态吸附实验研究了HKUST-1@H3PW12O40吸附低浓度铀溶液中铀（VI）的性能，考察了pH、干扰离子、吸附时间、铀初始浓度和温度等因素对吸附性能的影响。结果表明，Langmuir等温模型比Freundlich等温模型更适合于平衡数据的拟合。吸附动力学符合准二级动力学模型。吸附实验的热力学数据表明，吸附过程是自发的吸热过程。HKUST-1@H3PW12O40对多金属离子溶液中的U（VI）具有选择性吸附作用，经3次解吸-重复使用后，吸附容量没有明显下降。结果表明，HKUST-1@H3PW12O40适合于从低浓度溶液中去除U（VI）。
The adsorption of U(VI) from low concentration solution by HKUST-1@H3PW12O40was studied as a function of various experimental parameters including pH, interfering ions, contact time, initial uranium concentration and temperature by batch experiments. Equilibrium data were found to fit with Langmuir isotherm model better than Freundlich isotherm model. The kinetic adsorption was fitted by the pseudo-second-order model well. Thermodynamic data from the adsorption experiments indicate that adsorption process is spontaneous and endothermic. HKUST-1@H3PW12O40can selectively adsorb U(VI) from multi-metal ion solutions and the adsorption capacity of HKUST-1@H3PW12O40don’t decrease significantly after three cycles of desorption-reuse. The results show that HKUST-1@H3PW12O40is suitable for removal of U(VI) from low concentration solutions.
