Original language description
A macrohomogeneous mathematical model of the simultaneous transport of multiple ions across an ion exchange membrane based on the Nernst-Planck equation was developed. Schlögl's equation of motion was used to evaluate the convective term of the mass-transfer inside the membrane. The model accounts for the external diffusion of the ions through the Nernst diffusion layer to the phase boundary. Donnan equilibrium is used to describe the potential and the concentration discontinuity on the membrane-solution interface. The results document the importance of the external diffusion layers for ion transport across the membrane. The discrepancy between the model and experimental results was explained by the deviation of the input parameters from the real conditions and by neglecting ion activity coefficients in the membrane as well as in the free solution. The results obtained clearly indicate lower membrane selectivity compared with industrial applications. The model provides interesting info
