THE ANALYSIS OF ADSORPTION OF HEXADECYLPYRIDINIUM BROMIDES AND SODIUM ALKYLSULPHATES ON THE BINARY SOLUTION OF SURFACTANT — AIR INTERFACE

Abstract

It is experimentally shown, that the diluted binary solutions of hexadecylpyridinium bromides and sodium alkylsulphates (sodium decyl- and dodecylsulphates) find out synergism concerning decrease in a surface tension. The opportunity of definition of structure mixed adsorption layers by a method of the Rosen in which basis the theory of regular solutions lays, and the method of Hutchinson based on the equation of adsorption Gibbs is shown. Process of adsorption of surfactants of their binary solutions is thermodynamically more favourable process, than of adsorption of surfactants of individual solutions.
