摘要:
芳香聚酰胺纳滤膜不耐氧化,易被活性氯氧化降解,导致膜性能急剧下降,缩短膜的使用寿命,目前已成为制约芳香聚酰胺纳滤膜应用和发展的关键问题之一。本文综述了芳香聚酰胺纳滤膜的材料和结构,重点概述了芳香聚酰胺氯化和膜性能下降的机制,并进一步介绍了近年来耐氧化芳香聚酰胺纳滤膜的研究进展。
Abstract:
Aromatic polyamide thin-film composite(TFC)nanofiltration(NF)membranes are very sensitive to a chlorine disinfectant. The oxidative degradation takes place under active chlorine conditions. The free chlorine in feed stream can cause degradation of crosslinked aromatic polyamides and ultimately result in the decline of the membrane separation performance,which shortens the membrane life and greatly limits the further application and development of NF membranes. Series studies of NF materials and structures in recent years are briefly summarized. This review is focused on the oxidative degradation of aromatic polyamides and the mechanism of the decline of the membrane separation performance. The prospect on the development of the oxidation resistance of aromatic polyamide thin-film composite nanofiltration membranes is further analyzed.
