| Abstract |
The study reveals that the presence of molecular oxygen (oxic conditions) has a significant impact on the exhibited adsorptive capacity of granular activated carbon (GAC) for several phenolic compounds. The increase in the GAC adsorptive capacity under oxic condition results from polymarization of these adsorbates on the carbon surface. The mechanism of polymer formation is through oxidative coupling of phenolic molecules. The extent of an increase in the GAC adsorptive capacity is in accordance with the ease of oxidation of these compounds. However, substituting a nitro group on the parent phenol molecule suppressed polymerization reactions, and no increase in the GAC adsorptive capacity was observed under oxic conditions for these substituents. |
