Hydrazine nitrous acid scavenger

Nitrous acid also oxidises Pu and U. Thus, in order to obviate these difficulties, hydrazine is added as a scavenger for nitrous acid ... [Pg.456]

The formation of HN3 is undesirable as it is explosive and toxic. Goldacker reported [66] that a part of the small amount of HN3 produced is extracted in the aqueous phase, the remainder being removed by ventilation. However, these difficulties do not present intractable problems and so hydrazine is added to scavenge HN02 and prevent, inter alia, the nitrous-acid-driven re-oxidation of Pu(III) to Pu(IV) [72]. [Pg.456]

The scavenging of nitrous acid by hydrazine and by hydrazoic acid in solution of moderately high acidity (up to ca. 4 mol dm perchloric acid) has been examined. A paper has appeared claiming to produce kinetic evidence for the formation of substantial amounts of H2NO2+ in the reaction between nitrous acid and hydrogen peroxide. The evidence is basically deviations from the simple rate law (12). The... [Pg.140]
