The origin of the oxygen in plutonyl ion - the oxidation product of plutonium-(IV) with ozone in nitric acid solutions - has been investigated by IR spectroscopy (using oxygen-18). The observed number of oxygen atoms which have entered the plutonyl ion varies from 0.87 /plus minus/ 0.03 for 0.5 moles of HNO/sub 3/ per liter to 1.30 /plus minus/ 0.01 for 2 moles of HNO/sub 3/ per liter. The suggestion is made that in the oxidation of Pu(IV) by ozone, both atoms of oxygen originate from the ozone. Concurrently with the oxidation by ozone, a disproportionation of Pu(IV) takes place, which makes a further contribution to the overall oxidation process.
