The effect of molecular oxygen on the adsorptive capacity of activated carbon was evaluated in the study. It was determined that the capacity of granular activated carbon (GAC) for o-cresol under oxic conditions can be more than 2.5-fold the capacity attainable under anoxic conditions. This increase in the GAC adsorptive capacity under oxic conditions cannot be attributed to biological activity. The observed phenomenon was found to result from carbon mediated polymerization reactions of o-cresol that occur in the presence of molecular oxygen. The total exhibited GAC adsorptive capacity for the entire experiment was accurately predicted by the oxic adsorption isotherm. (Copyright (c) 1992 Water Environment Research, Washington, D.C.)
