The hydrogen and hydrogen peroxide produced in the radiolysis of CoIII-EDTA (CoIIIY−) in 0.8 N sulfuric acid have been measured. The yields of hydrogen and hydrogen peroxide were found to be G∞(H2)=0.4 and G∞(H2O2)=2.5 for the aerated system, G∞(H2)=3.2 and G∞(H2O2)=0 for the deaerated system where G∞ denotes the yield at the infinite solute concentration. The decomposition mechanism proposed previously was discussed in detail on the basis of the observed G∞(H2) and G∞(H2O2) and of the effect of chloride ion on the decomposition yield G∞(–CoIIIY−). A similar experiment was carried out for EDTA alone and the decomposition mechanism was discussed.
