Research output


Abstract: Results of calculating diffusion coefficients of ionic surfactants as functions of their concentration in micellar solutions have been analyzed within the framework of the quasi-chemical variant of the law of mass action. Diffusion coefficients have been evaluated for an ideal mixture of monomeric molecules and micelles, as well as taking into account the correction for the variability of the aggregation number of a surfactant using aqueous solutions of hexadecyltrimethylammonium bromide, hexadecylpyridinium chloride and bromide, and alkyltriphenylphosphonium bromides as examples.
