Equilibrium of counterion association in micellar systems: cetyltrimethylammoniumbromide

Surface Complexation Model was applied for the analysis of counterion association in the micellar systems. The equilibrium in cetyltrimethylammoniumbromide (CtaBr) solution was examined. Thermodynamic equilibrium constant was calculated using experimental data obtained with ion-selective electrodes (silver/silver bromide and surfactant electrode).
