An ESR spectroscopic study of the adsorption of Aerosol OT at the alumina/non-aqueous media interface

Abstract

Adsorption of Aerosol OT on alumina particles, preheated at 25°C or 300°C, from hexane and cyclohexanone was studied using two types of nitroxide probes. From the electron spin resonance spectra, the interaction between alumina surfaces having different amounts of water and Aerosol OT was discussed.
