Abstract:

The rates of formation of deuterium oxide in Co60 gammairradiated gaseous mixtures of deuterium and oxygen have been examined at initial deuterium concentrations, D2o, ranging from 0.00037 to 0.0037 molel. First- and zeroorder reaction rates with respect to deuterium were observed for the low and high D2o, respectively. The corresponding rate constants found were 0.0053hr and 0.0000045 molel hr at a dose rate of 5.61 x 10 to the 16th power evcc hr. The initial G values for deuterium oxide formation, GD2O, for the low and high D2o 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
