electroosmosis

[i‚lek·trō·äs′mō·səs]
(physical chemistry)
The movement in an electric field of liquid with respect to colloidal particles immobilized in a porous diaphragm or a single capillary tube.

Electroosmosis

 

(also electroendosmosis), the movement of a liquid through capillaries or porous diaphragms upon application of an external electric field. It is one of the principal electrokinetic phenomena. Electroosmosis is used to remove excess moisture from the soil in soil compaction for road building and the construction of hydraulic engineering installations, to dry peat, and to purify water and liquids used in industry.
