Colloids space charge polarization

Dielectric relaxation and dielectric losses of pure liquids, ionic solutions, solids, polymers and colloids will be discussed. Effect of electrolytes, relaxation of defects within crystals lattices, adsorbed phases, interfacial relaxation, space charge polarization, and the Maxwell-Wagner effect will be analyzed. Next, a brief overview of... 

Two effects which may be encountered during nonaqueous electrophoresis are space charge conditions and electrohydrodynamics (EHD). When an electric field is applied across a uniformly dispersed colloid the macroscopic charge density is zero and the field is uniform at the time of application. As the separation of opposite polarity charges occurs, a net internal... 

In practice, M or X are not evenly distributed but are influenced by the presence of P, the colloidal species and the more colloid or macroions present and the higher the charge they carry z, then the greater the unevenness of the distribution of the M ion. In practice, the membrane itself generally becomes polarized because of the macroions on one side and this is similar to the natural membranes in living systems. In dialysis, the Donnan equilibrium allows the removal of ions and traces of impurities. This is a fascinating topic that we do not have space to explore in detail in this monograph.
