Abstract

The kinetics of micelle formation of the binary mixture of the ionic and nonionic surfactants-- carboxymethylated neonol AF₉-6CM (72,7%) and neonol AF₉-6 (18,1%)--in aqueous solutions have been investigated using the ultrasonic relaxation technique. The dependence of the reciprocal relaxational time against total concentration of surfactant shows that minimum exists. And this minimum corresponds to the critical micelle concentration (CMC). The thermodynamic parameters of micelle formation have been estimated using the kinetic data. The minimum at the temperature dependence of CMC have been observed and it has been explained by the changes of the thermodynamic functions of micelle formation.
