In order to reduce environmental pollution from dyeing effluent, the cationic reverse micelles were prepared and used for removal of anionic Color Index (CI) Reactive Blue 19. The effect of surfactants, dyes, temperature and ultrasonic treatment on dye removal was investigated, respectively. The conductivity of CI Reactive Blue 19 aqueous solution was measured during removal process. In addition, the photograph of CI Reactive Blue 19 was also obtained. Finally, the removed dyes were backward extracted and reused for dyeing cotton fabrics. The results indicated that the removal of dyes was increased with increasing surfactants concentration and temperature, while the dye concentration exhibited the reverse trend. The higher removal of dyes could be caused by using ultrasonic treatment. The conductivity of dye aqueous solution was decreased with increasing surfactant concentration for the removal of dyes. The CI Reactive Blue 19 from backward extraction was reused for dyeing cotton fabrics, which exhibited the good property.
