Abstract

The structure of water in bis(2-ethylhexyl)sodium sulfosuccinate (AOT) micelles has been studied as a function of the [H2O]/[AOT] ratio (W) by using the absorption IR due to O-H stretching modes in the 3800–3000 cm−1 range. Two systems have been studied: water/AOT/carbon tetrachloride and water/AOT/n-heptane. The results show that IR spectra can be expressed as sum of contributions from interfacial and bulklike water. The fraction of water in the two “regions” within the water pool was evaluated as a function of W. From the data it appears that a continuous variation in the water properties inside micellar cores occurs rather than a two step hydration mechanism. The solubilization of water is described in terms of hydration of the AOT head group and Na+ counterions. The maximum hydration number of AOT was found to be 3 both in CCl4 and n-heptane.
