摘　　要：氧化石墨烯(GO)作为理想的膜构筑材料,因其蜂窝状的结构特点及表面分布大量含氧基团的特性,被广泛用于水处理分离膜的构筑。GO膜具有良好的物理特性、优异的化学稳定性和独特的二维层状结构,在污水处理、脱盐和离子筛分等水处理领域备受关注。在水处理中,GO膜对有机物和离子有较好的截留效果,但也存在水通量低、稳定性差等问题。本文分析了近年来GO膜在水处理领域的研究新进展;简单总结了GO膜的制备方法和水处理应用;重点阐述了GO水处理膜分离性能优化的方法和传质机理的研究进展;最后总结并展望了GO膜在结构调控和性能提升方面的发展方向。本文为设计和制备高性能GO水处理膜提供参考。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 twodimensional 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.
