J. Ennis et Lr. White, DYNAMIC STERN LAYER CONTRIBUTION TO THE FREQUENCY-DEPENDENT MOBILITY OF A SPHERICAL COLLOID PARTICLE - A LOW-ZETA-POTENTIAL ANALYTIC SOLUTION, Journal of colloid and interface science, 178(2), 1996, pp. 446-459
We examine the motion of an isolated spherical colloid particle with a
dynamic Stern layer, subject to an oscillating electric field, and ob
tain the electrophoretic mobility correct to O(zeta). It is shown that
the Stern layer results are formally similar to those for thin double
layers. From this, an approximation is derived for the Stern layer co
ntribution to the conductivity and mobility of particles with thin dou
ble layers and high surface potentials. (C) 1996 Academic Press, Inc.
