Review on the Construction of Graphene Oxide Separation Membrane and the Factors Affecting Its Permeation and Interception

膜分离技术对水资源的循环利用具有重要意义。氧化石墨烯(GO)构建的过滤膜具有可调节的纳米层间距,有利于实现膜通量与截留率的平衡。本文介绍了GO膜结构的构建方式及改性方法。在此基础上,进一步对影响GO膜渗透与截留的因素进行了综述。最后概述了GO膜在水处理中的应用,总结并展望了GO膜的发展方向,这对之后研究人员构建高质量的GO膜提供了一定的参考。

Membrane separation technology is of great significance to water resource recycling. As a filter membrane, the membrane has an adjustable nano-layer spacing, which is beneficial to achieve the balance of membrane flux and rejection rate. This paper introduces the construction and modification methods of GO membrane structure. On this basis, the factors affecting the permeation and interception of GO membrane were reviewed. Finally, the application of GO membrane in water treatment is summarized and the development direction of GO membrane is prospected,which provides a certain reference for researchers to construct high-quality GO membrane.
