Uranium tetroxide

Hydrogen peroxide pale-yellow precipitate of uranium tetroxide U04.2H20 (sometimes called uranium peroxide), soluble in ammonium carbonate solution with the formation of a deep-yellow solution. Chromium, titanium, and vanadium interfere with this otherwise sensitive test. 

Iodine is also given off to a small extent in dissolving the uranium metal in nitric acid, but larger amounts may be obtained on steam distillation after dissolution (5). Ruthenium is often removed from the fission products by distillation of the volatile tetroxide formed by oxidation with potassium permangate, sodium bismuthate, periodic acid (38) etc. The distillation goes readily and gives a product of good purity. 

Uranium reacts with dinitrogen tetroxide, N2O4, in acetonitrile to form an intermediate, U02(N03)2 N204 2CH3CN, which on heating above 160°C yields uranyl nitrate, U02(N03)2. 

In the belief that the action of the enzyme might be modified by the presence of some of the more prevalent metals in trace amounts, the effects of cations on mammalian /3-glucuronidase were re-investigated186 195 of a large number studied, only Cu , Ag , and Hg were pronounced in their effects. (Inhibition was also seen with uranium acetate, ammonium chloroplatinate, osmium tetroxide, and sodium tungstate.83) Marked inhibition was seen with 2.5 X 10-6 M of Ag and 1.5 X 10 6 M of Hg00, and inhibition by these two ions was reversed by tissue constituents.

The two chief oxides of uranium are the basic uranous oxide UO2 and the acid anhydride UO3. Intermediate between these two is a well-defined green oxide of composition UgOg. Less certain is the existence of a pentoxide UgOj, and a tetroxide, uranium peroxide, UO, though well-defined derivatives of the latter, peruranates, are known.
