Sažetak
In the first part the results of investigating interdependences
of parameters of the electroosmotic displacement process (ED) and
properties of adsorption layers of SAS have been considered. ED-
process, connected with flow of two immiscible liquids (»water«
and »oil«), filling the pores of diaphragm. Direct current is superimposed
on the water-containing part. The complex investigations
have been undertaken of the influence of SAS nature and concentration
on the displacement kinetics, oil output, wetting angle, surface
tension and the filtration velocity of oil with added SAS
through the diaphragms, the SAS-layers in which were formed
beforehand. In accordance with the results it follow that the character
of dependences, in which the effectivenes is reflected, is
very sensible to the change of adsorption layer properties, to their
stability, the velocity of destruction, the values of the primary and
residual wetting degree. In the second part the modifying action of
ionic surfactants using 2 types of interfaces: oxides (quartz) and
ion-exchange membrane have been considered and compared. The
adsorpiton of positive (CTA+) and negative (DS-) surfactant ions at
the quartz-aqueous solution interface, non-Langmuir type adsorption
isotherm, a change in the sign of ~ -potential of quartz in
CTAB solutions and surface conductivity in IEP are obse.rved. Ion-
exchange membranes in surfactant solutions exhibit a selective
adsorption (only surfactant counterions are sorbed), sorption isotherms
are of the Langmuir-type and as result of sorption of surfactant
counterions the ion-exchange membranes lose its high
permselectivity.
