Abstract In an attempt to determine the effects of molecular oxygen on activated carbon adsorption modeling, isotherms, microcolumns, and pilot-columns are completed in the presence and absence of molecular oxygen. The results show that in oxic conditions, natural organic matter has a higher adsorption capacity than in anoxic conditions. Molecular oxygen does not affect the adsorption capacity of target compounds in distilled water, however in the presence of natural organic matter, the adsorption capacity of the target compounds decrease in oxic conditions due to an increased competitive effect from the natural organic matter. The results also show that the constant-diffusivity scale-up approach is more accurate under these conditions than the linear-diffusivity scale-up approach.
