Oxidation of manganese(II) by ozone and reduction of manganese(III) by hydrogen peroxide in acidic solution

Abstract: the reaction involving formation of the manganese(II)-superoxide complex and reaction of H 2 O 2 with Mn(IV) species formed due to reversible disproportionation of Mn(III), is suggested.

“…Sheng (1993) made this hypothesis that the reaction between Mn 2+ and ozone produced Mn(III) and free OH radical based upon a theoretical study. Jacobsen et al (1998a) (Ruggaber et al, 1997) and we use available laboratory data (cross sections and quantum yields). Photodissociation coefficients at noon are shown in Table 6.…”

“…This may be because the reaction kinetics against ozone of these metals is different in each case, with Fe(II) and Mn(II) metals presenting the highest oxidation kinetics (Fig 3). The reaction mechanism plays a decisive role in the oxidation rate of metal species; thus, in the case of Fe(II) and Mn(II), it has been proposed that the oxidation process with ozone occurs by the formation of ions of great reactivity, such as FeO 2 + and MnO 2 + , respectively 21–26. The generation of these ions would explain the rapid oxidation of these metals.…”

“…In acidic solutions, Mn(II) can be oxidized to Mn(III), which in turn can be reduced back by hydrogen peroxide. The proposed mechanism involves an Mn(IV) intermediate that appears as a product of Mn(III) disproportionation [183]. Najafpour attempted a hypothesis that during the development of oxygen photosynthesis, a gradual increase in the complexity of plant and bacterial apparatus could be preceded by the functioning of some SOD-like complex [184].…”
