Abstract：As an excellent adsorbent material, graphene-based materials have superior adsorption capacity on various water pollutants including heavy metals and organic pollutants, which has received considerable attention due to its enormous potential in application of water treatment and groundwater remediation in recent years. The current research is generally still in the stage of laboratory simulation. The development of graphene-based materials with low cost, strong stability, easy recycling and environment friendly as well as high saturation adsorption capacity is the future developing trend. This review summarizes the classification and fabrication methods of graphene-based materials. Besides, the applications in water treatment and groundwater remediation are reviewed. Furthermore, the main problems at present and the application prospects for future research are proposed.
