potential is an abbreviation for electrokinetic potential in colloidal systems. In the colloidal chemistry literature, it is usually denoted using
the Greek letter zeta, hence ?-potential. From a theoretical viewpoint, zeta
potential is electric potential in the interfacial double layer (DL) at the
location of the slipping plane versus a point in the bulk
fluid away from the interface.
In other words, zeta potential is the potential difference between the
dispersion medium and the stationary layer of fluid attached to the dispersed
