Efficient Micellar Extraction of Ternary Mixture of Cationic Dyes from Aqueous Medium

Abstract

In the present work an attempt has been made to extract ternary mixture of Basic Yellow-2 (BY-2), Basic Red-12 (BR-12) and Basic Blue-26 (BB-26) dyes from simulated textile effluent by solvent extraction using anionic surfactant Sodium Dodecylsulfate (SDS). This study proposes an efficient, fast, simple and effective microemulsion system for the removal of cationic dyes using reverse micelles of anionic surfactant from wastewaters. In this method, dyes are dissolved in aqueous phase and mixed with organic solvent in the presence of surfactant. The effects of the concentration of feed mixture (dye and surfactant), temperature, pH and salt concentration on extraction of dyes from aqueous phase have been studied after the complete separation of two phases. The method poses no environmental threat, so it is an eco-friendly way to treat dye house effluents.
