Fluorometric Analysis of the Micelle Formation Process of Surfactants in Aqueous Solution. I. Utility of Pyrene in Determination of the Critical Micelle Concentration

Abstract

Pyrene, a fluorescent hydrocarbon, is a useful, sensitive probe for the determination of the critical micelle concentration of all types of detergents, non-ionic, anionic and cationic. In addition, this reagent has proved useful in research on the micelle formation process in aqueous solution and on differences in the rearrangement of the hydrocarbon chains of surfactants during micelle formation, based on measurements of the excimer formation efficiency.
