摘　　要：纳滤技术广泛应用于废水处理、水软化、食品加工及制药等行业,其中许多过程涉及酸性溶液的处理.商品化纳滤膜材料主要以聚酰胺为主,但聚酰胺在酸性环境中易水解而造成性能大幅下降,限制了其在酸性溶液中的应用,因此面向酸性溶液处理的耐酸纳滤膜应运而生.本文综述典型的耐酸膜材料,包括聚磺酰胺类、三嗪环类、磺化聚合物类和聚电解质类耐酸纳滤膜的研究进展和应用,重点分析了这几类膜材料的耐酸机理、膜结构调控规律以及如何通过构筑耐酸膜结构来实现膜耐酸性的提高.此外,本文还总结了耐酸纳滤膜在金属加工、矿业开采、造纸、食品加工及电镀等工业过程中的应用,为高性能耐酸纳滤膜的开发和应用提供指导.Nanofiltration has been widely used in wastewater treatment,water softening,food processing,and pharmaceutical industries et al.,many of these processes involve the treatment of acid solution.Commercial nanofiltration membrane material is mainly polyamide,which is readily hydrolyzed in acidic solution,limiting its application in acidic conditions.Therefore acid-resistant nanofiltration membrane has received wide attention.This article introduced the research progress of acid-resistant nanofiltration membrane materials and their application,including polysulfonamide,triazine ring-based polymer,sulfonated polymer,and polyelectrolyte.We focus on the acid resistance mechanism analysis of these materials and how to construct the pH-stable membrane structure to improve its acid resistance ability.The acid-resistant nanofiltration membrane has been used in metal processing,mining,papermaking,food processing and electroplating et al.
