Abstract

The rate of deposition of gas-phase SO₂ to a variety of aqueous solutions has been measured. The deposition rate is unaffected by relative humidity. Some salts may cause a 3-fold decrease in deposition rate as the ionic strength changes from 0.1 M to 0.8 M. Solution pH has the greatest influence causing a change from gas-phase diffusion control to solution phase diffusion control of deposition between pH 4 and pH 2. Indirect evidence has been obtained that suggests that the catalysis of SO₂ oxidation in solution by Mn(II) ions is slow with respect to SO₂ diffusion into solution. The practical implications of these results are discussed.
