Annotation:

The microenvironment of reverse micelles of sodium bis (2-ethylhexyl) sulfosuccinate was investigated by UV-visible spectroscopy on the basis of methyl orange as optical probe. The influence of nature of an oil phase and water to surfactant molar ratio, as well as the effect of kosmotropic and chaotropic nonionic additives in water nanocages of reverse micelle on absorption electronic spectra of methyl orange was investigated. The association degree of molecular probe to reversed micelles was determined.
