Abstract: |
|
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. |
