Cell theory of the electroosmosis in the concentrated diaphragms consisting of spheric particles of colloid dispersity with account of the insoluble boundary layer influence

Abstract

The electroosmotic transfer (ratio of velocity of liquid to electric current density) and conductivity of disperse system were calculated as functions of volume fraction of disperse particles. The considered model of electric double layer (EDL) was generalized by taking into account the reducing dissolving ability of liquid near the surface (non-dissolving boundary layer). The problem was solved for limiting case of large degree of EDL overlapping in interparticle space. The obtained results explain the main features of experimental data.
