Synthesis of core–shell structure UiO-66-NH2@Ni-MOF composite for the effective removal of uranium (VI)
The core–shell structure UiO-66-NH2@Ni-MOF was prepared by in-diffusion growth of 2D Ni-MOF on UiO-66-NH2 using PVP (polyvinylpyrrolidone) as a structural guide. It was applied to the adsorption of U(VI) in aqueous solution. The materials were characterized by powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive spectrometer (EDS). The UiO-66-NH2@Ni-MOF adsorption to U(VI) was investigated experimentally. The study showed that the adsorption of U(VI) onto UiO-66-NH2@Ni-MOF was endothermic and spontaneous. At pH 5.00 and 308 K, the adsorption capacity was 581.40 mg/g according to Langmuir model. In addition, the adsorption process can be described by the pseudo-second-order kinetic model. The adsorption capacity was kept at 83.83% of its original one after five sorption–desorption cycles, a promising indication for repetitive usage.
期刊介绍：
Journal of Industrial and Engineering Chemistry is published monthly in English by the Korean Society of Industrial and Engineering Chemistry. JIEC brings together multidisciplinary interests in one journal and is to disseminate information on all aspects of research and development in industrial and engineering chemistry. Contributions in the form of research articles, short communications, notes and reviews are considered for publication. The editors welcome original contributions that have not been and are not to be published elsewhere. Instruction to authors and a manuscript submissions form are printed at the end of each issue. Bulk reprints of individual articles can be ordered. This publication is partially supported by Korea Research Foundation and the Korean Federation of Science and Technology Societies.
