“…The resulting solution is passed through a membrane with pore sizes smaller than the micellar diameter, so that the micelles and solubilized organic solute are removed. Previous MEUF studies indicate that the separations (solute rejections) obtained are usually closely related to equilibrium values inferred from semiequilibrium dialysis (SED) Bhat et al, 1987;Smith et al, 1986;Higazy et al, 1987;Uchiyama et al, 1990, Correspondence concerning this article should be addressed to S.
