Abstract
The UV and visible spectra of pyrene complexed to paraquat in aqueous sodium dodecylsulphate (SDS) solutions have been studied as a function of the SDS concentration and the amount of pentanol solubilized in SDS micelles. The results have been analysed in terms of a change in the volume of solubilization of the complex and a partitioning of pyrene into a more alcoholic environment inside the micelle. This has led to a self-consistent interpretation of the complexation constant between pyrene and paraquat solubilized in SDS micelles.Keywords
