Dynamic dilational surface properties of submicellar multicomponent surfactant solutions. Part 2.—Thermodynamics of adsorption and comparison with experiment

Abstract

A hitherto unreported thermodynamic approach has permitted the prediction of the equilibrium surface tensions, elasticities and slopes of the adsorption isotherms for a submicellar solution of a binary mixture of similar nonionic surfactants from the correponding properties of solutions of the pure components. Agreement between theory and experiment for the surface dynamic dilational behaviour of the binary surfactant solution studied has also been demonstrated.
