The relatively low density of functional groups of graphene oxide (GO) and the difficulty to completely recover after adsorption limit its application in uranium (U(VI)) removal from aqueous solution. Inspired by a special chemical property, polydopamine (PDA) was first used as a surface modifying agent for GO, and then the as-formed [email protected] cross-linked with chitosan (CS) to assemble a three-dimensional (3D) porous [email protected]/CS aerogel for U(VI) adsorption. Morphology and structure of the aerogel were characterized by TEM, SE...
