摘　　要：为研发新型染色废水处理技术,采用反胶束萃取法对染色废水中阴离子水溶性活性染料进行移除和回收,研究染料浓度和结构对染料移除率的影响。采用离子交换模型模拟染料的移除过程,考察了染液中中性盐浓度和pH值等因素的影响,将回收的染料回用于棉织物的染色中。研究结果表明,反胶束萃取法对活性染料具有明显的移除效果,染料的移除率与染料分子结构有关,离子交换模型能较好地模拟染料的移除过程,中性盐浓度的增加有利于染料的移除,而pH值则表现出相反的变化趋势,回收的染料对棉织物具有较好的染色性能。In order to develop the new technology for the treatment of dyeing wastewater,the anionic water soluble reactive dyes were removed and reused by the extraction method using reverse micelles. The effect of concentration and structures of dyes on the dye removal were investigated,and the ionic exchange models were employed to fit the experimental data. Then the affecting factor such as pH values and salt concentration were also studied. Finally,the recovered dyes were reused for the dyeing cotton fabrics. The results showed that the reactive dyes could be removed by the extraction method. The removal process of dyes indicated the better agreement with the ionic exchange models equations. The increased salt concentration caused the improvement of dye removal. And the pH values exhibited reverse trend. The good dyeing property was obtained for the reused dyes.
