抄録

Micelles, consisting of an anionic surfactant (sodium linear alkylbenzene sulfonate) and a fatty acid released from a fat (linoleic acid), were separated from an aqueous phase using the natural clay mineral, allophane, based on its ion exchange characteristics. The adsorption process of these compounds by the allophane was determined by a UV spectroscopic analysis and by adding anthracene to the micelles as a molecule probe. The fluorescence measurement of anthracene made the study of the adsorption process easier. Furthermore, the fluorescence spectroscopic analysis using pyrene as a polarity probe revealed that the pyrene molecules existed in the lipophilic alkyl moiety of the anionic surfactant and fatty acid adsorbed on the allophane. This result indicated that these compounds were effectively adsorbed on the allophane, thus keeping their micelle form stable.
