zeta potentialnoun

Physical Chemistry.
  1. 1927–
    Electrokinetic potential, esp. (in a colloid) the electrokinetic potential at the interface between the dispersion medium and the layer of charged fluid particles surrounding a dispersed colloidal particle; cf. electrokinetic potential n. (b).

      They [sc. electrokinetic phenomena] arise whenever there is relative motion between a charged interface and a liquid and are usually interpreted in terms of the zeta potential.

      The zeta potential of apatites has thus been and still is considered to play a major role in the adsorption process.
