摘要：

In this study, a crystal material UIO-66-NH2-BPDA was designed by grafting BPDA onto UIO-66-NH2 and applied to extract U(VI) from aqueous solution. According to performance tests, UIO-66-NH2-BPDA exhibits excellent chemical and thermal stability. The experimental results show that U(VI) adsorption by UIO-66-NH2-BPDA was tested to be 346.58 mg g(-1) at pH = 4 and T = 298 K. The data simulation demonstrates that the adsorption process was consistent with Langmuir isotherm and pseudo-second-order model. Meanwhile, the thermodynamic parameters suggest that the adsorption process was spontaneous an...
