Abstract
Effect of urea on the fluorescence properties of p-toluidino naphthalene sulphonate (TNS) bound to triton-X and sodium dodecyl sulfate micelles has been studied. It is observed that on addition of urea, the critical micellar concentrations of the micelles increase and the fluorescence yield of TNS decreases considerably. The results are interpreted in terms of the model that urea displaces water molecules from the micellar interface and the consequent desolvation leads to removal of TNS molecules from the interfacial region.
