Electrophoresis in Concentrated Dispersions of Colloidal Particles

Abstract

A review is given on electrokinetic phenomena in dispersions of colloidal particles. Relationships between electrophoretic mobility and zeta potential (or particle charge) are given for various types of particles including hard particles, polyelectrolytes and soft particles. Static and dynamic electrophoresis in dilute and concentrated suspensions are discussed with particular emphasis on dynamic measurements in concentrated suspensions (that is, colloid vibration potential (CVP) method and electrokinetic sonic amplitude (ESA) method).
