Oxidation of SO2 in fog droplets by primary oxidants
Abstract Experiments described in this paper demonstrate that incomplete combustion is a source of gas-phase oxidants. These species, when dissolved in water, are manifested predominantly as H2O2. Experiments involving a fog chamber show that these primary oxidants oxidize SO2 to sulfuric acid or sulfate in fog droplets. Drying such fog droplets results in suspended particles. For a constant SO2 concentration and amount of fuel combusted, the amount of SO2 oxidized and the amount of oxidant produced depend critically on the combustion conditions, being highest for incomplete combustion and negligible for stoichiometric flames.
