Electrokinetics electrodialysis

Electrodialytic method Combines electrokinetic processes with electrodialysis membranes to remove contaminants from wet solids and aqueous solutions. 

Electrokinetic phenomena of the second kind have received mostly academic interest, but there may be important and unexpected applications. Already, second-kind electroosmosis has been implicated as a mechanism for superUmiting current in electrodialysis. Space-charge formation at nanochannel/microchannel junctions has also been exploited to trap biomolecules, although in that case the flow is undesirable since it interferes with trapping. The speed of second-kind electrophoresis may be useful in separation or mixing, but the need to apply a large DC voltage may limit its applicability.
