Oxidative decomposition of EDTA in aqueous solution under the action of ozone was studied. Conditions providing complete decomposition of EDTA and precipitation of radioactive cobalt in the form of hydroxide were found.

The oxidation of Fe2+, Mn2+, Co2+, Ce3+, and VO2+ by silver(II) has been investigated with a stopped-flow technique.The reactions of Mn2+ and Ce3+ occur through two competitive paths involving Ag2+ and AgOH+.For the other cations a single pathway with Ag2+ as oxidant has been observed.An inner-sphere interaction mechanism is proposed and discussed with reference to the electron configuration of the reductant and to the behaviour predicted by the Marcus cross relation.
Oxidation by aqueous fluoroxysulfate: Catalysis by silver(I)

The oxidations of the ions Cr3+, Co2+, and VO2+ by the fluoroxysulfate ion, SO4F-, in aqueous solution are catalyzed by Ag+. The rate-determining step for all three catalyzed reactions is the bimolecular oxidation of Ag+ by SO4F-, which has a rate constant of (1.3 ± 0.2) × 103 M-1 s-1 at 17°C. Activation parameters for this reaction are ΔH≠ = 6.1 ± 0.5 kcal/mol and ΔS = -23 ± 2 cal/(mol deg). In the absence of Ag+, Co2+ and VO2+ react very slowly with SO4F-, while Cr3+ does not react at all. Despite its high thermodynamic oxidizing power, the fluoroxysulfate ion acts as a very selective oxidant.
