A cleaning method for anion exchange membrane fouled by sodium polyacrylate

  • 摘要: 聚丙烯酸钠对阴离子交换膜的污染是影响双极膜电渗析回收丙烯酸丁酯废水中有机酸的关键因素之一。针对该问题研究开发了聚丙烯酸钠污染后离子交换膜的清洗方法,并采用膜电阻、迁移数、表面X射线光电子谱(XPS)分析等对膜清洗效果进行了表征。NaOH、NaCl和HCl溶液3种清洗液对离子交换膜的机械清洗及超声强化清洗效果表明,HCl溶液对聚丙烯酸钠污染阴离子交换膜的清洗效果最好,超声波可促进NaOH、NaCl和HCl溶液的清洗效果。采用2.0 mol/L的HCl溶液对受污染阴离子交换膜进行超声清洗,其膜电阻和迁移数可基本恢复到未污染膜的水平。
