Abstract
The interactions between phenazinium dyes and sodium dodecylsulphate, with concentrations of the surfactant near critical micelle concentration (CMC) in the sub-micellar concentration range, have been studied. It has been sug gested that the spectral bands, which were hitherto attributed to self-aggr egation of the dye, may actually be due to change in microenvironment of th e dye chromophore on incorporation of the dye into pre-micelles.
