Adsorption equilibria of binary mixtures of benzene and acetone vapors on graphitized carbon black
Adsorption isotherms of binary mixtures of acetone and benzene vapors on a graphitized carbon black (GCB) adsorbent were determined at 20/sup 0/C. Mass-spectrometric tracer pulse chromatography was used to measure the adsorption of each component at 70 different pressures of acetone and benzene to produce a full three-dimensional isotherm over the range up to, and slightly beyond, monolayer coverage. Each experiment was carried out at a fixed pressure of acetone and different pressures of benzene. The isotherms of benzene, at fixed acetone pressure, were fitted to the BET isotherm equation. Coadsorbed acetone had little or no effect on the benzene isotherms or the BET parameters; however, the isotherms of acetone were significantly influenced by coadsorption of benzene. Even the smallest amount of adsorbed benzene disproportionately diminished the extent of acetone adsorption. The retention volumes of small samples of two additional solutes, n-pentane and 1-propanol, were also determined at each isotherm point to determine the effect of the amount and composition of the binary condensed phase on the adsorption and retention of a third adsorbate at infinite dilution.
