摘要：
In this work, the graphene hydrogel (GH) was fabricated, and its adsorption behavior toward Th(IV) was studied. The GH displayed a porous network structure, with a controllable size and structure. The adsorption experimental results demonstrated that the adsorption of Th(IV) on GH fitted well with pseudo-second-order kinetic model and Freundlich isotherm model, with a maximum adsorption capacity of 190.28 mg/g at pH 3.0. The adsorption of Th(IV) on GH in inner-sphere surface complexation. Solution pH has an important influence on Th(IV) adsorption of GH. In addition, the GH exhibits an excellent reusability in Th(IV) adsorption.
