The oxidation of sulfur dioxide on carbon particles in dry air and in air at 65% relative humidity was greatly enhanced by the presence of gaseous nitrogen dioxide. Significant agglomeration and wetting occurred progressively during exposures at 65% relative humidity, and samples, even after 150 hr exposure, rarely reached steady state weight gain. Sorptions conducted in nitrogen atmospheres rather than in air appeared to produce slightly higher sorptions and weight retentions for equivalent exposure concentrations and times, indicating that NO2 acted as the oxidizer and that molecular oxygen in air may have weakly inhibited the oxidation by NO2.
