An experimental study of the oxidation of sulfur dioxide in aqueous manganese sulfate aerosols


A continuous stirred tank reactor is used to study growth of manganese sulfate (MnSO₄) aerosols due to catalytic oxidation of SO₂ in humid air. Humidities ranged from 91–97% and SO₂ concentrations from 0 to 92 ppm. The results of the growth studies are consistent with the rate expression for production of sulfuric acid: d[H₂SO₄]/dt = (8.3 ± 2.5) x 10⁻⁵/[H⁺]Ms⁻¹. This expression is estimated to hold for [Mn²⁺] ⩾ 0.O1 M and [SO₂] ⩾ 10 ppm.
