- Abstract：The application of graphene and its modified materials to remove heavy metals and radionuclides has received considerable attention in recent years, due to their large surface area, high adsorption capacity, and great radiation, thermal, acid and alkali resistance. In this paper, the synthesis and modification of graphene are introduced, and adsorption capacity, influencing factors, adsorption kinetics/thermodynamics and reaction mechanism for the removal of heavy metals and radioactive nuclides from aqueous solution by graphene and its modified materials are reviewed. Furthermore, the main problems and the future developing perspectives are presented.
