An ultrasonic relaxation has been found in solutions of the surfactants sodium decyl sulfate and decyltrimethylammonium bromide in various glycerol/water mixtures. By suing membrane electrodes selective to these surfactants, their critical micellar concentrations and also the monomer surfactant concentrations in micellar solutions have been evaluated. The relaxation has been attributed to the perturbation of the equilibrium between surfactant monomer and micelle. The combined relaxation/electrochemical data have been analyzed to investigate the kinetics of this process, using the Aniansson and Wall and Teubner equations and a phenomenological approach developed in this laboratory.
