Electrokinetic phenomena and colloids the zeta potential

A very useful type of phenomenon in the study of colloidal particles is the electrokinetic phenomenon that results from the movement of a solid phase with surface charge relative to an electrolyte-containing liquid phase. An applied electric field induces movement or, conversely, movement induces an electric field. The phenomena can be divided into two types  

These four manifestations of the electrokinetic effect are summarized in Table 3.2. 

Mobile phase Stationary phase Phenomenon Force applied Property measured 

Solid Liquid Electrophoresis Electric field Electrophoretic mobility via mass transport measurement, microscope or Doppler effect 

Solid Liquid Sedimentation potential Force of gravity Potential difference
