当聚酰胺（PA）反渗透（RO）膜暴露于氧化物质时，其性能会衰减，从而限制其使用寿命并增加运营成本。本文综述了氯的种类对聚丙烯酸膜性能和特性的影响。实验证据支持氯-聚合物相互作用的不同竞争机制将被提出，以及操作参数的影响。此外，概述了不同的改性方法，现有的使pa膜更耐氯。
Polyamide (PA) reverse osmosis (RO) membranes suffer performance decay when exposed to oxidizing species, limiting their lifetime and increasing operation costs. This article aims at reviewing the effect of chlorine species on the performance and characteristics of PA-membranes. Experimental evidence supporting different competing mechanisms for chlorine-polymer interaction will be presented, together with the influence of operational parameters. Additionally, an overview of different modification methods that exist to render PA-membranes more chlorine-resistant is given.
