Absolutely dry mineral was non-selective towards benzene, n-hexane and methanol.
Hydration inhibited sorption of hydrocarbons and promoted that of methanol.
Binary mixtures even hydrocarbon mixture equal by volume were sorbed competitively.
Benzene in the mixture was more active than n-hexane at all humidity levels.
Methanol was dominantly sorbed from benzene/methanol mixtures at all volume ratios.
