Electrical Aspects of Adsorbing Colloid Flotation. XVII. Quasi-Chemical Method for Adsorption of Mixed Surfactants

Abstract

The quasi-chemical approximation is applied to the calculation of adsorption isotherms for two-component surfactant systems. No further approximations are necessary. The effects of the relative sizes of the interaction energies of the various nearest neighbor pairs are investigated, and plots of representative adsorption isotherms are given. Some possible applications of the theory to foam flotation and other surface chemical separation techniques are suggested.
