Résumé du colloque

A study of water diffusion across polystyrenesulfonic acid ion-exchange membranes, induced by osmotic pressure and cation diffusion potentials, has been made. The experimental results have been interpreted in terms of viscous interactions within the membrane during the transport process, between the ion and water, and between the water and membrane pore wall. Equations have been derived which relate solvent and ion transport rates with the viscous interactions within the membrane. These relationships were used to estimate friction coefficients for the interchange processes. The dependence of the ion-water interaction coefficient on inorganic and organic counterion diameter was determined.
