摘      要：Absorption of phenol, catechol and resorcinol. which vary in their ability to interact with the adsorbent through hydrogen bond, were used to investigate the adsorption mechanistic interaction. The adsorption enthalpies of the above mentioned compound onto the adsorbent were calculated and thermodynamic analysis was carried out. The results showed the adsorbent with the lowest adsorption enthalpies for the sorbate such as catechol with intermolecular hydrogen bond also display the lowest adsorption affinity On the other hand the more of the groups available for hydrogen bond interaction. the higher of the adsorption affinity These observations support the contention that phenol adsorption is driven predominantly by specific interaction of the solute with active sites on the surface of the adsorbent.
