Abstract: A chromatographic method for study of effect of alcohol on micelle formation of nonionic surfactant in aqueous solution is described. The method, based on eluent gel permeation chromatography(E-GPC) , can detect critical micelle temperature(CMT) and micellemdlecule equilibrium of the system. The experiment shows the presence of benzyl alcohol decreases CMT of F127 aqueous solution up to 10℃ and makes micelle-molecule equilibrium shift towards micelle formation.
