Abstract

Critical micelle concentration data published for a given detergent show differences depending either on the nature of the organic molecule (dye) that was present during the determination, or on the determination method used. We studied the thionin monocation (ThH+) and the sodium dodecyl sulphate (SDS) system using spectrophotometric and spectrofluorimetric methods. It was established that the process of micelle formation could be followed by absorption spectra and the Rayleigh scattering of the system. Thionin in the micelle was stabilized in the monocationic form. Our results were checked by potentiometric measurements using a detergent-selective electrode developed in our laboratory.
