Research process on performance regulation and mass transfer mechanism of graphene oxide separation membrane

Due to the unique honeycomb structure with a large number of oxygen-containing groups, graphene oxide (GO) has been widely used as ideal construction blocks for water treatment separation membrane. GO membrane has good physical properties, excellent chemical stability and unique two-dimensional layered structure, which has attracted increasing attention in the fields of wastewater treatment, desalination, and ion sieving. In the water treatment processes, GO membrane shows good retention effect on organic matter and ions, however, meanwhile, the membrane itself suffers from some problems such as low water flux and poor stability. This paper reviews the current research progress of GO membrane in water treatment, including the preparation method and water treatment application of GO membrane, optimized method of separation performance and mass transfer mechanism on GO membrane. Finally, the development directions of GO membrane in structure regulation and performance improvement is summarized and prospected. It provides some references for designing and preparing GO membrane with high performance in water treatment.
