Primary electroviscous effect with a dynamic stern layer: Low kappa a results

The classical treatments of the primary electroviscous effect show importan t discrepancies with respect to the experimental data. A possible better ag reement may be found if the contribution of the ions adsorbed on the Stern layer, which can move tangentially near the particle surface, is taken into account. This contribution has been incorporated into the Watterson-White theory. A study of the influence of the Stern-layer parameters on the prima ry electroviscous coefficient has been made.
