▎ 摘　　要

In this present study, a graphene-based magnetic composite (Fe3O4/GO) was prepared and characterized by SEM, TEM, XRD and FTIR. The immobilization of U(VI) onto Fe3O4/GO by a adsorption process was using a batch technique. The pseudo-second-order kinetic and Langmuir isotherm model could best describe the adsorption kinetics and isotherms. The thermodynamic parameters calculated from the temperature dependent adsorption isotherms revealed that the adsorption of U(VI) on Fe3O4/GO was spontaneous and endothermic in nature. The as-prepared Fe3O4/GO composite may be utilized as an efficient, magnetically separable adsorbent for the removal of U(VI) and related radionuclides from aqueous solutions in nuclear waste management.
