NONLINEARITY OF ELECTROPHORESIS DETERMINED BY THE MOBILITY OF THE ADSORBED IONS - STRONG EXTERNAL-FIELD

An expression describing the distribution of the potential of the late ral face of the cylindrical particle aligned with the field was obtain ed. On the basis of the balance of the flows of ions within the area o f the most reduced adsorption and surface potential (one of the ends o f the particle), the estimate of the surface averaged value of the ele ctrokinetic potential was obtained. On this basis, the conditions were indicated that provide reduction of the electrokinetic potential from any high equilibrium value to 50-75 mV and under, and give rise to th e nonlinearity.
