反渗透（RO）脱盐是从海水和其他盐水源生产淡水的主要技术之一。反渗透脱盐过程中，膜性能对产水率和能耗有很大影响。近年来，人们在开发高性能反渗透膜方面做出了重大的研究努力。本文综述了近年来在提高反渗透膜通量、脱盐率、耐氯性、耐污染性和热稳定性方面的研究进展。重点介绍了现有高分子膜材料的改性，以及新型高分子膜、无机膜和混合基质膜的合成和分离性能。
Reverse osmosis (RO) desalination is one of the main technologies for producing fresh water from seawater and other saline water sources. The membrane properties greatly affect the water productivity and energy costs in the reverse osmosis desalinatin processes. Recent years have seen significant research efforts devoted to developing high-performance RO membranes. This article reviews recent activities in the development of RO membranes with improved flux and salt rejection, chlorine tolerance, fouling resistance and thermal stability. In particular, this review mainly focuses on the modification of current polymeric membrane materials, and synthesis and separation performance of new polymer membranes, inorganic membranes and mixed matrix membranes.
