URANIUM(VI) OXIDE(Cas 1344-58-7) Usage

Purification Methods

The oxide is dissolved in HClO4 (to give a uranium content of 5%), and the solution is adjusted to pH 2 by addition of dilute ammonia. Dropwise addition of 30% H2O2, with rapid stirring, precipitated U(VI) peroxide, the pH being held constant during the precipitation, by addition of small amounts of the ammonia solution. Then H2O2 is added until further quantities caused no change in pH. After stirring for 1hour, the slurry is filtered through coarse filter paper in a Büchner funnel, washed with 1% H2O2 acidified to pH 2 with HClO4, then heated at 350o for three days in a large platinum dish [Baes J Phys Chem 60 878 1956].
