- Abstract
The diffusion of alkali metals and ammonium chlorides through an OPMN-KM3 composite nanofiltration membrane is studied as a function of the electrolyte concentration on both sides of the membrane. A model is proposed for calculating diffusion coefficients that takes into account changes in the electrolyte concentration in selective pores of membrane. The diffusion coefficients are calculated both using the proposed model and by Fick's equation. The effect of the orientation of the membrane with respect to the diffusion flux on the diffusion coefficients of salts is analyzed.
