(Water Quality) In a Colloidal system, the difference in potential between the immovable layer attached to the surface of the dispersed phase and the dispersion medium. It is related to particle stability and therefore is a useful parameter in coagulation operations.

electrokinetic potential. Electric potential across all phase boundaries between solids and liquids. In colloids, the zeta potential is the potential across the ion layer around a charged colloidal particle. Neutralizing the zeta potential can cause the colloid to precipitate.

Zeta potential () is the electric potential at the surface of a colloidal particle relative to the potential in the bulk medium at a long distance. Also called electrokinetic potential. Zeta potential () is the potential across the interface of all solids and liquids. Specifically, the potential across the diffuse layer of ions surrounding a charged colloidal particle, which is largely responsible for colloidal stability. Also called electrokinetic potential.

The electrical potential difference between the surface (strictly the slip plane) of a latex particle and the bulk of the aqueous phase. Theoretically this is a measure of the colloidal stability of a latex, i.e. the higher the zeta potential the higher the stability of the latex. However, this theory does not appear to apply to natural latex concentrate.

The electrical potential which exists across the interface of all solids and liquids.
