Ye. Solomentsev et Vm. Starov, EFFECT OF CHARGED GEL LAYERS ON ELECTROKINETIC PHENOMENA - ELECTROOSMOSIS, Colloid journal of the Russian Academy of Sciences, 54(4), 1992, pp. 591-598
The problem of flow of a solution of a binary electrolyte in a straigh
t cylindrical capillary having walls coated with a porous charged or u
ncharged gel layer under an applied electric field was solved. It was
shown that electrokinetic phenomena are possible when there are no fix
ed charges both in the gel itself and on the initial surface due to sp
ecific interaction of ions with the gel material.
