摘要：
The surface excess and the heat of immersion in the adsorption from binary mixtures on the active carbon surface were calculated in terms of the concentrations of adsorbed phase, the adsorption capacity ratios and the heats of immersion of pure compounds. The surface concentrations of binary mixtures were obtained from the thermodynamic model incorporating the intermolecular interactions between the surface and bulk molecules, and a model for surface activity coefficient considering the orientational states of adsorbed molecules, and the UN1QUAC equation. The calculated adsorption isotherms and heats of immersion were fair agreement with experiments of various binary isotherms. © 1990, Taylor & Francis Group, LLC. All rights reserved.
