摘要：Textile batik industry produces wastewater which contributes to water pollution since it utilizes a lot of organic and inorganic chemicals especially dyes. Decolourization of wastewater is very important before discharged. This study explores the liquid-liquid extraction method to recover or to remove Black B dye from batik industry wastewater using tridodecylamine (TDA) in kerosene. The important parameters governing the extraction behaviour of Black B have been investigated such as pH of the source phase, extractant concentration, dye concentration and stripping agent. The experiment was carried out in batch process. Almost 98% of dye was extracted using 0.04 M TDA and pH 4 of source phase. The extraction of dye decreased as the pH of solution increased. The dye loaded in organic phase was back extracted using various types of in organic acid s and bases as stripping agent. The result found that almost 100% of dye was stripped using 0.5 M Thiourea in 1 M sodium hydroxide solution. As a conclusion, Black B dye recovered successfully using TDA in kerosene at favourable condition.
