In this paper, the effect of ethylene glycol (E.G.) on solubilization of NaCI aqueous solution in perchloroethylene solution of Aerosol OT (A. OT) was investigated by means of turbidity method. It was shown that the maximum amount of solubilization of NaCI aqueous solution was less than that of non-NaCI aqueous solution in previous paper. As A. OT concentration was increased, solubilization ratio (S/So) of NaCI aqueous solution was decreased. But the maximum amount of solubilization of NaCl aqueous solution containing E.G increased more than in case of non-E.G. media, and this tendency was more remarkable when E.G. content in this solution increased. From these results, the mechanism of increase of maximum amount of solubilization of NaCI-E.G, aqueous solution was explained by the effect of common ion of Na from A.OT and NaCI in A.OT micell in perchloroethylene.
