An approximate analytic expression for the electrophoretic mobility of a spherical colloidal particle in a symmetrical electrolyte solution is obtained. This mobility expression, which is correct to the order of the third power of the ΞΆ-potential of the particle, considerably improves Henry's mobili

An approximate analytic expression for the surface charge density/surface potential relationship (/ 0 ) for a spherical colloidal particle in a solution of mixed and nonsymmetrical electrolytes is obtained by solving a nonlinear Poisson-Boltzmann equation using a linearization approximation. The app
A model is developed to simultaneously account for both a nonuniform zeta potential \((\xi)\) on the surface and polarization of the double layer in computing the electrophoretic motion of a spherical particle. The double layer is assumed thin \((\kappa R \gg 1\) where \(\kappa\) is the Debye parame
