摘要：

In this paper, a modified thermodynamic equation to predict interfacial tension (IFT) at oil/water interfaces with the presence of ionic surfactants and salt is considered. The surfactant activity coefficient is optimized based on the Extended UNIQUAC model according to the experimental results and is used in the modified model. In this study, the effect of salt with the presence of surfactants such as DTAB, M12 L12, SDBS and PFSA in the water/oil system has been considered to investigate the interfacial tension. According to the results of this study, the proposed equation can present a reasonable description of oil/water IFT measurements in the presence of cationic or anionic surfactant solutions and in a range of added salt.
