摘要: |
|
全芳香聚酰胺反渗透复合膜(简称全芳香PA膜)因合成简便、分离效率高,被广泛用于水处理领域。为缓解微生物污染,通常投加含氯杀菌剂,导致水体中普遍存在游离氯。而全芳香PA膜受游离氯攻击易降解,降低其选择性与使用寿命。针对这一挑战,耐氯全芳香PA膜的开发成为近年来的研究热点,大量新型耐氯全芳香PA膜被报道。但基于全芳香PA膜氯化降解机理对其研究进展进行系统综述的文献很少。基于此,本文从全芳香PA膜氯化降解机理及耐氯机制出发,论述了近年来耐氯全芳香PA膜的设计策略及研究进展,总结了耐氯全芳香PA膜研究面临的主要挑战,提出了未来的研究方向,以期为新型高性能耐氯全芳香PA膜的持续发展提供参考和理论支撑。 |

Polyamide (PA) membranes have been widely applied in water treatment owing to their facile synthesis, excellent chemical resistance, and high separation efficiency. To mitigate biofouling, chlorine-containing disinfectants are commonly added during operation, resulting in the widespread presence of active chlorine in aqueous environments. However, PA membranes are highly susceptible to degradation upon exposure to active chlorine, leading to reduced selectivity and shortened service life. To address this challenge, the development of chlorine-resistant PA membranes has become a major research focus in recent years, and numerous novel chlorine-resistant membranes have been reported. However, few studies have systematically reviewed the research progress based on the chlorination degradation mechanisms of PA membranes. Based on this, this review first elucidates the chlorination degradation pathways and chlorine-resistant mechanisms of PA membranes, followed by a comprehensive discussion of recent design strategies and advances in chlorine-resistant PA membranes. Furthermore, the main challenges in this field are summarized, and potential future research directions are proposed to provide theoretical guidance and reference for the continuous development of high-performance chlorine-resistant PA membranes. |
