| 摘 要： | 针对稀溶液的相平衡的特点,提出了适用于气液色谱法测定模型的稀溶液活度系数表达式。将稀溶液汽液平衡关系引入色谱测定方程中,得到大为简化的工作方程,计算结果与原方程吻合用上述处理方法,分析了考虑压力影响的Valentin和Guiochon的色谱测定方程。

Revised Models for Gas Chromatographic Measurements of Vapor Liquid Equilibria of Dilute Solutions |
| |
| Abstract: | In this paper expressions for activity coefficients of dilute solutions are derived, which are suitable for working equations for vapor liquid equilibrium measurements by gas chromatography. By virtue of using the expressions for dilute solutions the working equations are significantly simplified, and the calculation results are in good agreement with those obtained from the original ones. Moreover, the pressure effects on the VLE results are evaluated by means of the same procedure. |
