Studies on recovery of silk dyes from textile effluent by liquid liquid extraction and liquid membrane processes

Abstract

A major source of release of colour into the environment is newlineassociated with the incomplete exhaustion of dyes in dyeing effluent and the newlineneed to reduce the amount of residual dye in textile effluent has thus become newlinea major concern in recent years Hence the textile effluent should be treated newlinein such a way to recover the unfixed dye before discharging it into the newlineenvironment newlineMembrane technology is one of the most important topics in todays newlineresearch Studies on liquid membranes have been developed and studied for newlinethe separation of organics and valuable metals from their low concentration newlinesources Hence it was felt that it is essential to develop and investigate new newlinemethods employing liquidliquid extraction and liquid membrane for removal newlineand recovery of acid and basic silk dyes from textile wastewater by using newlinecationic and anionic carrie newline newline
