Kinetics of surface-catalyzed oxidation of sulphur(IV) by dioxygen in aqueous suspensions of cobalt(II) oxide

Kinetics of the Iron(II)- and Manganese(II)-Catalyzed Oxidation of S(IV) in Seawater with Acetic Buffer: A Study of Seawater Desulfurization Process

“…Most of the previous studies found no dissolved oxygen dependence in both uncatalyzed and catalyzed oxidation. But there are exceptions, for example, 0.5 reported by Zhang and 1 reported by Prasad . The pH dependence was also studied by a number of researchers, and the results are also quite different from each other. ,,,, The most complicated issue of the S(IV) oxidation process is the catalytic and redox effects of different transition metals.…”

Inhibiting Effect of Different Carboxylic Acid on Uncatalysed and Co2O3 Catalysed Autoxidation of SO2 in Alkaline Medium- Brief Comparision

“…Recent studies show that the sulfur (IV) oxidation in atmospheric water droplets can be affected by other reactions. Organic compounds may dissolve into water droplets and react with sulfoxy radicals and transition metal ions, and thus alter the rate of catalytic S(IV) oxidation [11][12][13][14][15]. In most of the studies the role of organics has been reported in the metal ion catalysed autoxidation of sulfur (IV) in aqueous medium [16][17].…”

Kinetics of the uninhibited and ethanol-inhibited CoO, Co2O3 and Ni2O3 catalyzed autoxidation of sulfur(IV) in alkaline medium

“…In this connection, the catalytic role of several metal oxides such as CoO [2], Co 2 O 3 [3], Ni 2 O 3 [4], CuO [5], MnO 2 [6] and Cu 2 O [7] in acidic medium has been examined in detail. In the case of the first five oxides, the kinetics agreed with the rate law (1).…”
