説明

Abstract In this paper, the effects of α, β‐cyclodextrins (β‐CD) on the critical micelle concentration (CMC) of CTAB, SDS, and Brij35 were investigated at 25°C using electrical conductivity and visible spectrophotometry. The results indicate that α, β‐CD increase the CMC of the surfactants by the competitive inclusion of surfactant in cyclodextrin. From the experimental data, an empirical formula for CMC* (apparent critical micelle concentration) of these three surfactants was obtained.
