The rate of adsorption of SO 2 on a prototype carbonaceous surface was measured at low pressure in a flow reactor. The measured rate indicates a maximum atmospheric loss of SO 2 by heterogeneous reaction of 1%/h for a particle density of 100 μg/m 3 . The capacity of carbon particles to adsorb SO 2 is limited at ∼1 mg SO 2 g −1 C. NO 2 has no effect on the rate of SO 2 adsorption or the saturation behavior.
