Fig. 5 shows the effect of different diluents such as toluene,
benzene, xylene and dichloroethane on the percentage of dye
extraction. All the experiments were performed using 30 mg/l
initial dye concentration, pH equal 11, 1:1 extraction phase
ratio, 0.06 M extractant concentration and 25 min equilibrium
time. The maximum degree of extraction of the dye (100%)
was achieved with dichloroethane. Therefore, succeeding tests
were carried out using dichloroethane as diluents
