The diffusion of a substance through a membrane in an electric field; formerly called electroendosmosis. Compare: electrodialysis.

electroosmosis (i·lekˈ·trō·z·mōˑ·sis),

n process by which a conducting liquid moves through a porous membrane because of a difference in potential between the two electrodes on opposite sides of the membrane.

As the present work is concerned with electric fields operating at frequencies of 1 MHz and high conductivity media, the effect of AC electroosmosis is considered negligible and will not be covered (Morgan and Green, 2003).
He found that electroosmosis could reduce draft energy--the energy needed to pull a tiller through soil--by almost 40 percent in loam.
In fact, Hoenig says, electroosmosis would facilitate tilling at up to roughly 16 kilometers per hour, "which is a typical plowing speed.
Even under the best conditions, however, energy savings from electroosmosis averaged a mere 11 percent in clay.
Electroosmosis should be able to draw buried chemicals to degradation zones (lower diagram) in just a week or two, Brodsky says.

Contributions of electromigration and electroosmosis to iontophoretic drug delivery.
Two major transport mechanisms are involved: electromigration and electroosmosis.
Electroosmosis is the principal transport mechanism of uncharged molecules and of high-molecular-weight cations.
In this system, the velocity of electroosmosis exceeds the electrophoretic mobilities of the protein fractions, leading to a cathodal migration of the molecules, which are then detected and quantified in the far UV.
