Non-Equilibrium Thermodynamics of Electroosmosis of Liquid Mixtures Studies on Aqueous n-Propanol

Abstract

Electroosmotic transport processes of aqueous n-propanol through a pyrex sintered glass membrane (porosity G 4) are reported. The data are analyzed in the light of non-equilibrium thermodynamics. The concentration dependence of the phenomenological coefficients has been shown to be in conformity with the structural modifications. The efficiencies of electrokinetic energy conversion for both electroosmosis and streaming potential have been evaluated and the results thus obtained have been shown to be consistent with the steady state thermodynamic theories. The tightness of the coupling between the flows of matter and electricity has been examined.

Concentration Dependence of Transport Coefficients of Binary and Ternary Mixtures Through Inactive Membranes

“…The experimental values of L 21 [16], yield that Onsager's reciprocity relation holds well. Furthermore, there is a parallelism between the L 21 and the D/τ?…”

“…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.…”

Electrokinetic Effects off Aqueous Acetone Transmitting Supported Lipid Membranes

“…Studies on electrokinetic effects of liquid mixtures through a pyrex sintered G 4 disc, ion-exchange and inorganic membranes, have been reported in literature [1][2][3][4][5]. The data have been analysed in terms of non-equilibrium thermodynamics.…”
