通过测定不同覆盖度下的甲苯－正己烷、苯－正己烷、丙酮－正已烷和正戊烷－正己烷４个二组分气体在灯黑上的组成吸附等温线，发现它们有着共同的规律：随着覆盖度的增加，各体系的组成吸附等温线都向上靠近它们各自的气液平衡曲线。因此，基本上可以把二组分的气相与吸附相的平衡看成二组分的气液平衡，４个体系的组成吸附等温线基本上都可以通过理想溶液的相对挥发度方程式模拟得到。
The compositional adsorption isotherms of four binary gases of toluene-n-hexane, benzene-n-hexane, acetone-n-hexane and n-pentane-n-hexane under different coverage were measured on lamp black and found that they all had the same rule : With the increase of coverage, the adsorption isotherms of each system are close to their respective gas-liquid equilibrium curves. Therefore, basically, the equilibrium between gas phase and adsorbed phase of the two components can be regarded as the gas-liquid equilibrium of the two components. The adsorption isotherm of the four systems can basically be simulated by the relative volatility equation of the ideal solution.
