Wan Badhi, Wan Ahmad and Suhaimi, Hamdan and Ibrahim, Ramli and Hassan, Senin (1995) Kinetic and Equilibrium Studies on the Exchange Process of n-Hexanol and Cetyl Trimethyl Ammonium Bromide (CTAB) Micelles. Pertanika Journal of Science & Technology, 3 (2). pp. 221-232. ISSN 0128-7680
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.
