Notes:
The sorption of dissolved oxygen on activated carbon was characterized with manometric and packed column apparatus. All carbons tested, granular and powdered, virgin and reactivated, sorbed 150 to 600 μmole of oxygen/g after run times up to 1 700 hr., but sitll not at equilibrium. The rate data generally conform to a model of sorption limited by intraparticle diffusion. Carboxylic acid groups increase by about 200 μeq/g as a result of dissolved oxygen sorption, which can account for at least 10 to 50% of the oxygen sorbed. Also, about 5% of the sorbed oxygen can be eluted into deoxygenated water.
