Ultrasonic relaxation studies of the exchange process between surface active agent ions, small molecules and mixed micelles

Abstract

The ultrasonic relaxation method has been used to monitor the rates of the dynamic equilibrium between surface active agent ions, small molecules including alcohols, an aldehyde, an acid and a surfactant micelle. These data have been interpreted in terms of a model in which the kinetics of the exchange process are governed by the principles of the Langmuir adsorption theory. In all cases the correspondence between theory and experiment is good.
