1873 J. C. Maxwell Treat. Electr. & Magnetism II. vii. 206 We may now confine our attention to that part of the kinetic energy of the system which depends on the squares and products of the strengths of the electric currents. We may call this the Electrokinetic Energy of the system.
1916 J. E. Boodin Realistic Universe iii. 40 The rate at which this conserved energy varies with the current is called the ‘electrokinetic momentum’ of this circuit.
1926 W. A. Perlzweig tr. L. Michaelis Hydrogen Ion Concentration x. 248 Adsorption potentials cannot yet be recognized in any other way except through electrokinetic phenomena (electrophoresis, electroendosmosis, hydrodynamic currents and currents of falling particles).
1989 Jrnl. Colloid & Interface Sci. 129 55/1 Since electrokinetic behavior may be correlated with urinary transport..all aspects of electrokinetic studies acquire great significance.
2007 Materials Sci. & Engin. A. 447 91/2 It was initially thought that the inclusion of solid particles depends on their mobility and electrokinetic nature in the plating solution.
Compounds
electrokinetic potential n. (a) Physics rare potential energy associated with moving charged particles; (b) Physical Chemistry the electric potential at the interface between a (conducting) fluid and a charged solid body moving within that fluid, relative to a hypothetical point in the fluid located an infinite distance from the solid body; cf. zeta potential n. at zeta n.1 Compounds 2.

1911 Proc. Royal Soc. A. 85 44 A1, A2, A3 represent the components of electro-kinetic potential.
1925 Chem. Abstr. 19 770 An equation is derived expressing the theories of polarization-capacity, of the electro-capillary curve, and of the electro-kinetic potential.
1970 J. J. Bikerman Physical Surfaces iv. 162 For almost unprotected emulsions, rapid coagulation was said to occur as soon as their electrokinetic potential ζ..descended below 0.03 volt.
1998 G. Cecchine et al. Pesticides IV. vii. 80 Deposition and retention of pesticide-bearing particulates appeared to depend on mechanical restrictions related to fabric weave and on the electrokinetic potential of fabric surfaces.
