Many materials with varied characteristics have been used for water purification and separation applications. Recently discovered graphene oxide (GO), a two-dimensional derivative of graphene has been considered as a promising membrane material for water purification due to its excellent hydrophilicity, high water permeability, and excellent ionic/molecular separation properties. This review is focussed on the possible versatile applicability of GO membranes. It is also known that selective reduction of GO results in membranes with a pore size of ∼0.35 nm, ideally suited for desalination applications. This article presents the applicability of graphene-based membranes for multiple separation applications. This is indeed the first review article outlining a comparison of GO and r-GO membranes and discussing the suitability for applications based on the porosity of the membranes.
许多具有不同特性的材料已被用于水净化和分离应用。最近发现的氧化石墨烯（GO），作为石墨烯的二维衍生物，因其优异的亲水性、高水渗透性和出色的离子/分子分离性能，被认为是一种有前途的水净化膜材料。这篇综述聚焦于氧化石墨烯膜可能的广泛适用性。还已知对氧化石墨烯进行选择性还原会得到孔径约为0.35纳米的膜，非常适合海水淡化应用。本文介绍了基于石墨烯的膜在多种分离应用中的适用性。这确实是第一篇概述氧化石墨烯膜和还原氧化石墨烯膜比较并基于膜的孔隙率讨论其应用适用性的综述文章。
