- This study presents the synergistic liquid-liquid extraction (LLE) of turquoise blue dye through the formulation of synergist extractants in the organic liquid phase, their extraction mechanism, as well as the selection of the best stripping agent. The results showed that a single extractant provides 60% extraction performance at a concentration of 0.1 M. The extraction has increased remarkably to 94% using a synergistic system containing 0.08 M trioctylamine (TOA) and 0.01 M dialkyl phosphinic acid (Cyanex 302) with the highest synergistic coefficient of 4.77. Meanwhile, sodium hydroxide (NaOH, 0.1 M) was chosen as the best stripping agent where almost 100% of stripping efficiency was obtained. Thus, the synergistic formulation containing TOA and Cyanex 302 in LLE offers great potential for the high efficiency of dyes removal from the textile industry effluent.
