Micellar Electrokinetic Chromatography Estimation of Critical Micellar Concentration of Sodium Dodecyl Sulphate Systems in Saline Media

Abstract Micellar Electrokinetic Chromatography was applied to the estimation of the critical micellar concentration of sodium dodecyl sulphate in saline media of different nature (2-(N-cyclo-hexylamino)-ethanesulphonic acid and Ammonium Acetate) and concentration. The linear variation of the capacity factor for two series of compounds (11 benzene and naphthalene derivatives and 17 1,4-dihydropyridines) as a function of sodium dodecyl sulphate concentration in the electrolytic solution allowed this estimation.
