Abstract

Kinetic studies using ultrasonic relaxation method in the mixed micellar solutions of n-hexanol dan cetyl trimethyl ammonium bromide have shown a well-defined single relaxation. This is associated with the exchange process involving the partitioning of alcohol with the mixed micelle. The equilibrium measurement which monitors the monomer concentration of n-hexanol was measured using head space analysis involving gas chromatography. The combined relaxation and equilibrium data were analysed using a phenomenological treatment in which the kinetics and thermodynamics parameters were evaluated for the exchange process. The main conclusion from this work is that the association of n-hexanol to the the mixed micelles is almost a diffusion controlled process.
