Abstract:

CMC (Critical Micelle Concentration) is an important parameter of surfactant. It has been reported that it changes with ionic strength, temperature, additives, etc. Therefore, it could not be overestimated to develop the determination method of CMC of surfactants. Recently,current method using CE instrument and CE method have been reported. This paper presents an new method for determining CMC of anionic surfactants by ligand exchange micellar electrokinetic chromatography.
