Several phenolic compounds undergo polymerization on the granular activated carbon surface when oxygen is present in the test environment. Furthermore, appreciable increases in the exhibited adsorptive capacity of GAC for these compounds were observed as a result of this polymerization process. In the present study it was revealed that many of the reported discrepancies on multicomponent equilibrium may be related to monomer transformations that occur in the presence of molecular oxygen. In this work, the effectiveness of the ideal adsorbed solution theory (IAST) model in predicting multicomponent equilibrium is examined for the oxic and anoxic conditions.
