Electrokinetic Effects

An important consequence of the existence of electrical charges on surfaces is that particles will be affected by an applied electric field
These are collectively defined as electrokinetic effects

There are distinct effects depending on the way in which the motion is induced

Electrophoresis: the movement of a charged particle relative to the liquid it it suspended in under the influence of an applied electric field
Electroosmosis: the movement of a liquid relative to a stationary charged surface under the influence of an electric field
