Abstract
In this study, cationic dye namely methyl violet (MV) from aqueous solution by liquid–liquid extraction (LLE) has been investigated. Toluic acid demonstrated to be a very effective extractant for selective extraction of methyl violet from aqueous solution. The various diluents used were benzene, xylene hexane, toluene, kerosene. Among them, xylene was found to be the most effective diluent for extraction of methyl violet dye. The maximum extraction efficiency (99.0%) was obtained at pH 12.0 ± 0.1. The other influencing parameters were also examined: effect of pH in feed phase, toluic acid concentration in organic phase, effect of diluents, acid concentration in strip phase and stripping phase ratio. The extracted dye has been successfully stripped by 0.5 N HCl. Real effluent was also extracted and found to give satisfactory result.
