| 摘 要： | 对于水溶液中表面活性剂分子在表面相达到吸附平衡时,Rosen[1]等人导出了如下相平衡计算方程式中α:活度,上标:s:表面相、b:体相,bo:参考态.αibo:单一的i组分水溶液在其表面张力与系统表面张力相等时的体相活度.在Rosen等人的工作中对表面相的处理采用单参数的Margules活度系数关联式,对每一个实验点都求出一个参数β值,所得β值并不是一个常数。 |

| Abstract: | In this paper the Margules two parameters equation were used to correlate the nonidcal properties of surface phase, and a method was suggested to calculate the surface tensions and the surface excess mole fractions of the binary surfactants aqueous solutions. It was found that the calculated values of surface tensions were in good agreement with the literature values and their average errors were smaller than 0.5mN/m for three systems calculated. |
