Abstract

Effect of anionic polyelectrolyte sodium carboxymethylcellulose on surface tension of alkyl sulphate derivatives of sulphoacid solutions, sodium dodecyl sulphate and ammonium dodecyl sulphate, has been investigated. It has been established that the compositions of surfactants–sodium carboxymethylcellulose show an appreciable synergetic effect of surface tension decrease. The values of surface activity and kinetic adsorption constants of the associates of surfactants with NaCMC at the interface liquid-gas were determined.
