Abstract
Previously reported results by the authors revealed that the presence of molecular oxygen (oxic conditions) in the test environment can, in some instances, cause an almost threefold increase in the adsorptive capacity of granular activated carbon (GAC) for phenolic compounds. The polymers formed as a result of these oxidative coupling reactions under oxic conditions are very difficult to desorb from the surface of GAC. This led to significant irreversible adsorption in the presence of moolecular oxygen. On the other hand, when the same compounds are adsorbed on the carbon surface under anoxic conditions, essentially all of the adsorbate can be recovered from the carbon surface by solvent extraction.
