Nonlinear effects in the electrophoresis of a spherical colloidal particle Article uri icon

abstract

  • The reduced electrophoretic mobility-reduced zeta potential relationship for a charged macroparticle is shown to be nonuniversal and to be highly nonlinear. In agreement with experimental results, a mobility reversal due to the macroion’s charge inversion and a nonlinear dependence of the mobility on salt concentration is obtained. © 1999 The American Physical Society.
