Abstract

The critical micelle concentrations (CMC) of some sodium alkyl sulfates (SNS, SdS, SDS, STS, and SHS), sodium dodecyl sulfonate (SDSO), CTAB and Triton X-100 were determined by measuring both the absorbance and the absorption wavelength of vitamin A in aqueous solutions of surfactants of various concentrations. The results are in agreement with those obtained by other methods in the literature. The influence of micelles upon the absorption spectra of vitamin A have been investigated. The effects of the temperature and the incubation time on the measurements have been discussed.
