Cloud point extraction (CPE) is carried out to extractMaxilloneGoldenYellow( MGY) dye fromaqueous solution using non-ionic surfactant, TX-114. The effects of different operating parameters, e.g., concentrations of surfactant, dye and salt, temperature, pH on extraction of both dye and surfactant have been studied in detail. The extraction of dye increases with temperature, surfactant concentration and salt concentration. It has been observed that 95.3-90.01 percentMGY is possible for the feed dye concentration of up to 500 ppmusing pH 11, 0.7%of TritonX-114 (W/V), and 0.6(M) of salt (KCl) at 65 °C for 15 min. It is concluded that the cloud point extraction techniques for the dye removal may be an alternative to the present dye removal processes.
