摘要：
The effect of additives of butanol-1 on micellization of sodium dodecyl sulfate in an aqueous solution was studied by fluorescence spectroscopy using pyrene as a fluorescent probe. The critical micelle concentration of the surfactant was established to decrease in increasing content of alcohol. On the basis of data on fluorescence quenching hexadecylpyridinium bromide micelle quantitative parameters - the number of aggregation, the radius of the micelles, the area of hydrophilic groups and the critical packing parameter were calculated. Spherical mixed micelles with size smaller than in water were shown to form in the presence of 1-butanol in aqueous solutions of sodium dodecyl.
