摘要: Nuclear energy is a clean and reliable alternative to traditional fuels such as gasoline and coal. However, the treatment of wastewater from nuclear plants is an issue that needs wildly exploration. In this study, novel cerium (Ce) modified aminated MOF UiO-66 was synthesized through solvothermal reactions. Using ZrCl4 as a sacrificial template, the target product Ce-UiO-66-NH2 had been prepared by hydrothermal process. The microscopic surface morphology and characterized structure were investigated by BET, SEM, and FTIR characteristic protocols. The results revealed that Ce and amino groups have been successfully introduced on the surface of UiO-66. The absorbent Ce-UiO-66-NH2 showed its maximum specific surface area, with 823 m(2)/g. And the average pore size was 0.52 and 0.47 cm(3)/g for Ce-UiO-66 and Ce-UiO-66-NH2, respectively. For the SEM results, both absorbents showed spherical structure, with the particles presenting 0.2-0.5 mu m size core-shell structures. Considering the FTIR spectra, the characteristic peaks were located at 1656, 1569, 1385, 963, 894 cm(-1) wavenumbers, indicating the incorporation of Ce and -NH2. The absorbance effect was highly enhanced by suitable functionalization of the material by introducing addition metal element Ce and amino group and thus more binding storage can be used in nuclear wastewater treatment.
