Adsorption equilibrium data of binary liquid mixtures containing n-alkanes, cycloalkanes, and 1-alkanols on activated carbons

Surface excess isotherms of seven binary liquid mixtures with hexane, 2,2,4 -trimethylpentane (isooctane), cyclohexane, methylcyclohexane, ethanol, 1-p ropanol, and 2-ethylhexanol on several activated carbons at 298.15 K are pr esented. The surface excess depends on the accessibility of the pore system and on the interaction energies between adsorbate and adsorbent which can be extremely high due to superficial polar groups. For future modelling the characterization of the adsorbents is extended by Boehm titrations in orde r to determine the concentration of polar functional surface groups.
