The impact of the characteristics of granular activated carbon (GAC) on adsorption capacity and on the potential for polymerization of phenolic compounds on the surface of GAC in the presence of molecular oxygen is evaluated in the study. Adsorption isotherm data were collected for p-chlorophenol on five activated carbons, three manufactured from bituminous coal, one manufactured from lignite coal, and one manufactured from wood. These isotherms were collected under anoxic (absence of molecular oxygen) and oxic (presence of molecular oxygen) conditions. Higher extraction efficiencies of the carbons used in the oxic isotherms were obtained for the carbons that exhibited lower increases in capacities when compared to anoxic isotherms.
