Transient electrophoresis of a spherical colloidal particle with a slip surface

Abstract

We derive the general expression for the transient electrophoretic mobility of a spherical colloidal particle with a slip surface in an electrolyte solution. From the general mobility expression, we derive an analytic mobility expression, which is applicable for low particle zeta potentials and arbitrary Debye length. This expression corresponds to the time-dependent transient Henry function.

Keywords: slip surface; spherical colloidal particle; transient electrophoresis; transient electrophoretic mobility.
