Measurement of Adsorption Isotherms for Mixed Vapors

A great deal of work has been done in the measurement of adsorption isotherms of pure gases and vapors, but very little of the measurement of adsorption isotherms of mixed gases or vapors and much of this has been unintentional, being due to impurities in the adsorbate. Papers dealing with measurements of this type include those of Richardson and Woodhouse (2) and Bakr and King. (3) The method of Bakr and King has the objection that each experiment yields an isolated value. Richardson\u27s and Woodhouse’s method requires extensive gas analysis and yields an isotherm in which the composition of the adsorbate changes
