Ultrasound studies of critical micellar concentrations of ionic surfactants

Abstract

Aqueous solutions of the salts of alkylphosphoric acid are studied by acoustic method. The measuerments of the ultrasound's velocity V and density (rho) in aqueous solutions of CINTAF-108H at temperature ranges from 283 to 313 K and concentration intervals 0.15 to 0.3 kg/m3 were carried out. The data of critical micelle concentration and thermodynamic parameters are determined.
