摘要：
In this work, a novel three dimensional graphene oxide sponge composite material was synthesized by functionalized GO sheets with phytic acid (PA). The as-synthesized samples were characterized and employed to investigate the removal of U(VI) from aqueous solution. Results show that higher pH favored the sorption of uranium on PA–GO. Ionic strength puts insignificant influence on the sorption. The maximum adsorption capacity is 124.3 mg g−1 at pH 5.5. The adsorption isotherms can be well described by Langmuir isotherm model and the sorption kinetics has been successfully modeled by pseudo-second-order kinetic model.
