Description
Summary:A hydrothermal and ethanol activation method is proposed to synthesize Cu-BTC and graphite oxide composites (Cu-BTC/GO). The uranium dynamic adsorption behavior was investigated by varying the addition of graphene oxide. The result showed that Langmuir isotherm and quasi-secondary kinetic model (R 2  > 0.99) were more consistent with the adsorption process of uranium (VI) on this composite, and the maximum uranium adsorption was 150.50 mg g −1 . The thermodynamic parameters indicated that this adsorption process was spontaneous and endothermic. After five adsorption–desorption cycles, the adsorption efficiency can still reach 76.6–78.9%. This study will help to draw a promising roadmap to describe the adsorption performance of Cu-BTC/GO composites for uranium.
