摘要：

By extending the scaled particle theory (SPT) with six conditions adapted to Carnahan-Starling equation of state, SPT6-CS, (D. W. Siderius, D. S. Corti. J. Chem. Phys. 127, 144502 (2007)) a new expression for surface tension prediction of binary mixtures was obtained. The results of calculations are compared with those obtained from the SPT with three conditions, SPT3 (J. L. Lebowitz, E. Helfland, E. Praestgaard. J. Chem. Phys., 43, 774 (1965)). The results revealed that in spite of their simplicity, the studied models are in fairly good agreement with the experimental data. In addition, the results show that the obtained expression fitted very well with surface tension experimental data of binary alkane mixtures at different temperatures.
