| Abstract |
Adsorptive capacity of granular activated carbon (GAC) for several organic compounds was found to be strongly influenced by the presence of molecular oxygen. As a result, GAC exhibits much higher adsorptive capacities for these compounds under aerobic than anaerobic conditions. Therefore, a new experimental procedure for conducting an adsorption isotherm test is proposed in this work. The results of kinetic experiments show that this polymerization of adsorbate proceeds at a very slow rate that extends the time required for equilibrium conditions to be established. Extraction efficiencies obtained for GAC used in anaerobic isotherm experiments were significantly higher than those obtained for GAC used in isotherm experiments conducted in the presence of molecular oxygen. |
