Sulfuric and aerated solutions of peroxyvanadic ions containing nonperoxided pentavalent vanadium were irradiated by Co/sup 60/ gamma rays. The reduction yields of either ionic species was dependent on their relative concentrations, while the total reduction yield of tetrayalent vanadium is independent of it (G/sub VO2+ = 6.5). The quantitative interpretation of the results was made by adopting the same hypothesis which was necessary to explain the reduction of nonperoxided V/sup 5+/ ions alone (J. chim. phys. 54, 659(1957)). Moreover, two chemical reactions should be considered in the chemical calculations: the catalytic decomposition of peroxyvanadic ions in the presence of tetravalent vanadium and the oxidation of the tetravalent ions by oxygenated water.
