Abstract

Textile wastewater containing dyes is dangerous to the environment and affect mainly to some aquatic life. Their concentration must be reduced to acceptable levels before discharging into environment. In this research liquid-liquid extraction method is used to study on the recovery of Remazol Brilliant Orange 3R dye (orange 3R) from textile wastewater by using tetrabutyl ammonium bromide in dichloromethane. The parameter examined in this research were the effect of diluents, effect of pH, effect of extractant concentration, initial dye concentration and the suitable stripping agent to extract back the dye from organic phase. The result showed that almost 100% of 100 mgL-1 Orange 3R was extracted using 0.01 M tetrabutylammonium bromide (TBAB) and no significant affect of pH of feed phase solution on dye extraction. Extracted dye in the organic phase can be back extracted using salicylic acid in sodium hydroxide solution with ratio 1:1.
