Manganese(II)- and Nickel(II)-Catalyzed Oxidation of S(IV) by Oxygen in Aqueous Solution : A contribution to subproject HALIPP

• Manganese(II)- and nickel(II)-catalyzed oxidation of sulfur(IV) by oxygen in aqueous solution at pH 4.5 has been studied, as a model for oxidation of sulfur(IV) to sulfuric acid at the natural pH of the droplets in most atmospheric aqueous systems.

• Experiments on manganese(II)- and nickel(II)-catalyzed oxidation of sulfur(IV) by oxygen in aqueous solution at pH 4.5 afford a direct measurement of the loss of sulfur(IV) during the oxidation in the natural pH-range of most atmospheric aqueous systems.
