Abstract

A cloud point extraction as tool for separation red BG 46 in waste samples

Author(s): Mehdi Alizadeh, Mehdi Askari

An attempt has been made to remove color from waste water containing Red BG 46 (a cationic dye) by surfactant mediated 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 94.6-91.5 percent Red BG46 is possible for the feed dye concentration of up to 500ppm using pH 10, 0.6 % of Triton X-114 (W/ V),and 0.4 (M) of salt (KCl) at 65ï‚°C.
