Sorption of volatile organic compounds and their mixtures on montmorillonite at different humidity

- 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.
