CO60 GAMMA-RADIOLYSIS OF DEUTERIUM-OXYGEN MIXTURES,
Abstract
The rates of formation of deuterium oxide in Co60 gammairradiated gaseous mixtures of deuterium and oxygen have been examined at initial deuterium concentrations, (D2)o, ranging from 0.00037 to 0.0037 mole/l. First- and zeroorder reaction rates with respect to deuterium were observed for the low and high (D2)o, respectively. The corresponding rate constants found were 0.0053/hr and 0.0000045 mole/l hr at a dose rate of 5.61 x 10 to the 16th power ev/cc hr. The initial G values for deuterium oxide formation, G(D2O), for the low and high (D2)o were 2.9 and 7.3, respectively. A search for reaction products other than deuterium oxide, using ferrous sulfate and titanium sulfate reagents, established that (a) no deuterium peroxide was formed as a stable reaction product and (b) a wallstabilized species, whose identity was not extablished, was observed; it oxidized the ferrous sulfate reagent but did not react with the titanium sulfate reagent. An 8-fold change in the surface-to-volume ratio of the irradiation vessel did not significantly affect the concentration of this species. (Author)
