Micelle-mediated extraction as tool for separation blue RGL 42 in waste samples

M.Fathimadabadi, M.Daroon, F.Ahmadi

An attempt has been made to remove color from waste water containing Blue RGL 42 (a cationic dye) by surfactantmediated cloud point extraction (CPE) in batch mode using Triton X-114 as non-ionic surfactant. Most of the dye molecules get solubilized in the coacervate phase leaving a dye free dilute phase. The effects of different operating parameters such as concentration of surfactant, salt, temperature and pH on the removal of dye were studied in details and a set of optimum conditions were obtained. It has been observed that 94.5-91.02 percent Blue RGL 42 is possible for the feed dye concentration of up to 500 ppm using pH 9, 0.015(M) of TX-114 and 0.1(M) of salt (KCl) at 650C.
