Abstract
Microelectrophoresis has been used for more than 60 years to study the behavior of aluminosilicate clays, yet there is still widespread disagreement concerning the ability of this simple measurement to describe the nature of the aqueous/solid interface. The disagreement stems from questions regarding the validity of the equations used to transform the measured property, electrophoretic mobility (µ), into the zeta potential (ζ). In electrophoresis, ζ is the average electrostatic potential at the shear plane between a hydrated particle moving in response to an electric field and the stationary water through which the particle moves. To make the mathematical analysis of the forces involved in electrophoresis tractable, the shear plane must be defined as an imaginary plane separating the hydration sheath of the moving particle from the bulk water in which it is moving (Hunter, 1981).
