Abstract

Particle formation from NH₃-SO₂ reactions at trace water vapor concentrations has been studied experimentally and theoretically. Three possible solid products—NH₃SO₂, (NH₃)₂SO₂, and (NH₄)₂S₂O₅—were considered, and calculations were carried out to predict equilibrium concentrations of the reactants. A gas to particle conversion model for the NH₃-SO₂ system was developed, considering simultaneous chemical reaction, nucleation, condensation, and coagulation. Potential applications of this system of reactions are also discussed.
