Abstract
Adsorption isotherms for phenol and o‐cresol on activated charcoal at neutral pH and several dissolved oxygen concentrations were conducted at 23°C. Significant improvement in capacities were observed with increasing dissolved oxygen concentrations for the two adsorbates. These statistically‐significant additional capacities were not due to biological activities but merely due to surface chemical reactions. The improvement in capacity was directly related to the amount of oxygen per unit mass of GAC.Keywords
