“Zeta Potential”  

  Zeta Potential is the charge that develops at the interface between a solid surface and its liquid medium. Zeta Potential is measured in MilliVolts, may arise by any of several mechanisms.
  Zeta Potential may arise by any of several mechanisms. Among the mechanisms are the dissociation of ionogenic groups in the particle surface and the differential adsorption of solution ions into the surface region. The net charge at the particle surface affects the ion distribution in the nearby region, increasing the concentration of counterions close to the surface. Thus, an electrical double layer is formed in the region of the particle-liquid interface. *
