ABSTRACT
Critical micelle concentrations [cmc's] of the ionic surfactant dodecyltriethanolammonium iodide have been studied spectrophotometrically in water-ethylene glycol [EG] mixtures [XEG = 0.0, 0.093, 0.120, 0.290, 0.552 and 1 at 25, 35 and 45C]. The equilibrium model of micelle formation is selected to determine the thermodynamic parameters delta G, delta H and delta S. An interpretation of structural changes in H2O-EG system has been suggested
