反渗透是重要的海水淡化技术，本文针对反渗透膜易被水中活性氯破坏导致性能下降的问题，介绍了聚酰胺反渗透膜氯化降解理论，并深入探讨了国内外对耐氯反渗透膜材料的研究与开发现状，讨论了耐氯反渗透膜的研究方向和发展前景。

Reverse osmosis technology plays an important role in desalination industry. However, regular reverse osmosis (polyamide) membrane will be damaged by active chlorine in feed then fail in separation performance. Here the chlorination mechanism of reverse osmosis polyamide membrane is briefly illustrated and the progress in new chlorine-resistant membrane materials is reviewed.
