| Abstract: | The dynamics of a decrease in the surface tension is studied for aqueous solutions of sodium dodecyl sulfate and its mixtures
with lower alcohols (ethanol and n-propanol). Two approaches are analyzed as applied to the estimation of the adsorption of two surfactants from their mixed
solutions at a liquid—gas interface, i.e., the Frumkin generalized model and the Fainerman—Miller model. It is shown that
both approaches adequately describe the concentration dependences experimentally measured for the surface tension of sodium
dodecyl sulfate—lower alcohol mixtures. |
