Abstract:

Using the chromophore base of benzene sulfonate in sodium dodecyl benzene sulfonate(SDBS), the aggregation property of SDBS with non-ionic surfactant TritonX-100 in aqueous solution was studied by fluorescence. Results show there are two turning points in the variation curve of fluorescence intensity I as a function of concentration, which is the critical micelle concentration and the concentration at which the micelle shape changed, respectively. The interaction parameter βM between SDBS and TritonX-100 was calculated by the formula of mixed micelle interaction. The results show there is synergism and strong interaction between them.

Key words: Intrinsic fluorescence, Interaction, Mixed micelle, Critical micelle concentration, Surface tension
