Micelle-mediated extraction as tool for separation blue RGL 42 in waste samples
Author(s): M.Fathimadabadi, M.Daroon, F.AhmadiAn 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.
