Polyamide (PA) membrane is extensively used in various membrane separation processes due to its easy preparation, high selectivity and good acid-base stability. However, the PA material is vulnerable to the attack of free chlorine which causes PA chlorination degradation and eventually damages the membrane selectivity. As such, developing chlorine-resistant membrane has become a research focus in membrane technology recently. This accelerates the emergence of a large number of novel PA membranes. However, reviews on this aspect are quite rare to date. Thus, providing an updated critical review on the PA-based anti-chlorine membrane is highly needed. This paper aims to critically review the recent development in the PA chlorine-resistant membrane designed specially via the modification of the PA selective layer. The recent advances in the PA anti-chlorine membranes are briefly introduced first. The mechanism and influential factors of the chlorination of PA membrane are subsequently presented. The strengths and limitations of the recently developed PA anti-chlorine membrane are critically evaluated afterward. The challenges and future research directions of the sustainably chlorine-resistant PA membranes are finally discussed. This article can provide insightful guidance for the future development of the PA-based chlorine-resistant membrane.

聚酰胺基耐氯膜的最新进展和未来挑战

聚酰胺（PA）膜因其制备简单、选择性高、酸碱稳定性好等优点，广泛应用于各种膜分离过程。然而，PA材料容易受到游离氯的攻击，导致PA氯化降解，最终损害膜的选择性。因此，开发耐氯膜已成为近年来膜技术的研究热点。这加速了新型PA膜的大量出现。然而，迄今为止，这方面的评论还很少。因此，非常需要对基于 PA 的抗氯膜进行最新的严格审查。本文旨在综述通过对PA选择性层进行改性而专门设计的PA耐氯膜的最新进展。首先简要介绍PA抗氯膜的最新进展。随后介绍了PA膜氯化的机理和影响因素。随后对最近开发的 PA 抗氯膜的优点和局限性进行了严格评估。最后讨论了可持续耐氯PA膜面临的挑战和未来的研究方向。本文可为PA基耐氯膜的未来发展提供富有洞察力的指导。
