Effects of metals and surface functional groups on adsorptive properties of GAC
- Univ. of Pittsburgh, PA (United States). Dept. of Civil and Environmental Engineering
This study evaluated the mechanisms responsible for the catalytic behavior of granular activated carbon (GAC) in the presence of oxygen, which was previously documented in the case of aromatic organic compounds. Oxygen-containing functional groups as well as metals and metal oxide complexes on the GAC surface are being investigated for their role in promoting oxidative coupling of phenolics under oxic conditions. This study is utilizing a virgin bituminous coal-based carbon and versions of the same carbon whose metals were removed by acid-washing or surface functional groups removed by outgassing. Freundich isotherm parameters and solvent extraction efficiencies for the virgin and modified version of this carbon have shown that the removal of oxygen-containing functional groups or metals and their complexes does not have a significant impact on adsorptive properties exhibited in the presence of molecular oxygen.
