Abstract: Graphene oxide (GO) composite membranes have attracted much attention in the field of membrane separation due to their excellent hydrophilicity, abundant functional groups, large specific surface area and chemical stability. In this paper, the preparation methods of GO composite membranes were reviewed, including vacuum filtration, spin coating, layer-by-layer self-assembly, doping method and blending. Meanwhile, the research progress of GO composite membranes in the field of water treatment (micro-polluted water treatment and advanced treatment of industrial wastewater) was introduced. In addition, the separation mechanism of pollutants by GO composite membranes was discussed. Finally, the application prospects and future research directions of GO composite membranes in the field of water treatment were prospected.
