Comparative Study of Liquid –Liquid Extraction and Bulk Liquid Membrane for Rhodamine B

In the liquid liquid extraction (LLE) the extraction of rhodamine B (RB) from aqueous solutions by using 0.8M phenol in xylene was studied. The influencing parameters such as the effect of pH of the aqueous phase, the effect of extractant concentration, the effect of diluents and the stripping reagents has been investigated. The maximum extraction efficiency was obtained at pH 1±0.1 and the maximum stripping efficiency of dye from loaded organic dye was obtained using 10M acetic acid concentration. In the liquid membranes (LM), the above optimum conditions were applied and carried out further experiments. The extraction and stripping process were carried out in single step it is called pertraction process. The influence of pH of the aqueous donor phase, phenol concentration in the membrane phase, the effect of stripping reagents in the received phase rate of stirring speed, transport mechanism has been investigated.
