New Development on Analysis of Ionic Transport across Ion-exchange Membrane

Abstract

The transport phenomena across the ion-exchange membrane in organic solvent and in low water content were analyzed on the basis of the Donnan equilibrium and the Nernst-Planck equation of ion flux considering the Fuoss ion-pair formalism, and the theoretical predictions agreed well with the experimental data. The theoretical prediction clarifies the charge effectiveness parameter (Q-value) and the ionic mobility are the function of dielectric constant. This theoretical treatment can be applied to “Fuel cell system using methanol (DMFC) ”, “Fuel cell system in low water content”, “Metal recovery from waste water with organic solvent”, “Highly salt condensation”, and “Ionic transport across ionic channel”.
