“…on x is non-linear. Moreover, some investigators [6][7]21] employing systems similar to Srivastava's one, have recently obtained non-linearities in the dependences of L ll3 L 12 and L 21 on the composition. M. L. Srivastava and Lai [22], have shown, on the other hand, that the concentration dependence of L u and L 12 with x must be linear if the interaction amongst the components of the mixture as well as the alteration in the membrane-permeant interaction with changes in the composition were negligible.…”

An experimental investigation on the electrokinetic transport of ternary and binary mixtures through inactive membranes is described. Pyrex glass and quartz were used to perform the porous membranes. The phenomenological equations between the thermodynamic fluxes and forces were always found to be linear. The geometric parameters of the porous membranes were found to be independent on the composition of the mixture. The concentration dependence of the coefficients L 21 and L 22 in the Pyrex-binary mixture systems was non-linear. A similar dependence was found for D/T? (D, dielectric constant; τ?, absolute viscosity) with the composition of the binary mixture. The concentration dependence of the L n and L 22 coefficients was linear for the quartz-ternary mixture systems. Similar trends were found for the reciprocal of the absolute viscosity (η"" 1 ) and the specific electrical conductivity (λ) of the ternary mixtures. Onsager's reciprocity relation was experimentally verified and found to be obeyed within the experimental error. The variations of the coefficients L 12 and L 21 with the composition of the ternary mixtures was non-linear, although less pronounced than that obtained for the binary mixtures. The results confirm the decisive influence of the physical properties of the liquid mixture on the actual values of the electrokinetic transport coefficients.

Electrokinetic phenomena like hydraulic permeability, electroosmosis, streaming potential and current of water -acetone mixtures of different compositions, through cephalin and phosphatidyl inositol membranes, supported by a pyrex sintered G 4 glass disc, have been studied. The results obtained have been analysed with the help of non-equilibrium thermodynamics. Onsager's reciprocal relation has found to be valid and the efficiency of the electrokinetic energy conversion for electroosmosis and the streaming potential has been calculated. The concentration dependence of the phenomenological coefficients L l± and L 12 has also been taken into account.
