▎ 摘  要

The performance of a magnetic chitosan/graphene oxide composites (MCGO) have been investigated for the adsorption processes of U(VI) ions from aqueous solution. The synthesized nanocomposites were characterized by infrared spectra (IR), scanning electron microscopy (SEM) and X-ray diffraction (XRD). The influences of the pH of solution and the contact time on the adsorption amounts have been discussed, and the optimal experimental conditions for the adsorption of U(VI) have been obtained. Experimental equilibrium data has been obtained and the kinetic results revealed that pseudo-first order kinetic model provided the best description of the equilibrium data.
