摘要：

Adsorption excess isotherms were determined on planar surfaces and porous adsorbents in methanol-benzene and benzene-n-heptane mixtures. These functions give Δ21G = f(x1) adsorption displacement free energy functions, which are characteristic of the polarities of the surfaces. Adsorption displacement enthalpy isotherms were also determined through immersion wetting and flow microcalorimetry measurements and, thus, entropy changes could be calculated as well. New equations are given for molar adsorption displacement energy and adsorption capacity calculations via the combination of enthalpy and free energy isotherms with adsorption excess isotherms. © 1991.
