摘要
The surface adsorption and micellization of the mixed aqueous solution of C7FNa-Et4NBr system have been studied by the determination and analysis of surface tension-concentration relation. The results show that (1) the surface activity of C7FNa could be greatlyenhanced due to the addition of Et4NBr(in comparison with the addition of inorganic salt, NH4Cl)By analyzing the results of surface adsorption data and the characteristics of relevant components, the rational explanations for this phenomenon have been made;(2)the thermodynamic functionsfor the mixed system, have been obtained by utilizing the mass action lawmodel of micellization;the rules of these quantities are quite similar to the case of a common single surfactant.
