zeta_potential



Colloidal particles dispersed in a solution are electrically charged due to their ionic characteristics and dipolar attributes.  Each particle dispersed in a solution is surrounded by oppositely charged ions called the fixed layer. Outside the fixed layer, there are varying compositions of ions of opposite polarities, forming a cloud-like area. This area is called the diffuse double layer, and the whole area is electrically neutral. When a voltage is applied to the solution in which particles are dispersed, particles are attracted to the electrode of the opposite polarity, accompanied by the fixed layer and part of the diffuse double layer, or internal side of the "sliding surface".    ||  Dispersed particles Aggregated particles  ||  Zeta potential is considered to be the electric potential of this inner area including this conceptual"sliding surface". As this electric potential approaches zero, particles tend to aggregate.
