文摘

There is no universality in the mobility versus z-potential curves. There is a non-linear behavior of the mobility vs the surface charge density of the colloidal particle. The Modified Poisson-Boltzmann Theory predicts a reversed mobility, something that has been demonstrated experimentally.Electrophoresis studies though the Modified Poisson-Boltzmann.
