Graphene is an advanced carbon material with two-dimentional nanostructure, high specific surface area and high electrical conductivity. Benefiting from its structure, graphene has been attracted a lot of attention and regarded as an exciting material which can be used in the fields of water treatment. In this paper, the structural characteristics and preparation methods of graphene are introduced systematically, and its performance in water treatment, such as capacitive deionization, adsorption and filtration separation, are reviewed. At the end, the existing problems and the future development of graphene as the water treatment material are also put forward.
