THE DETERMINATION OF BROMINE IN URANIUM HEXAFLUORIDE

Technical Report ·
OSTI ID:4313175
The uranium hexafluoride is sampled in a silver vessel and hydrolyzed with water, which dissolves or hydrolyzes the bromine compounds. After a reduction with sulfur dioxide, the bromine is precipitated as silver bromide and collected on silver chloride. The bromide is convented to soluble potassium bromide by treatment with potassium hydroxide and hydrogen peroxide. The bromide is oxidized to bromate with sodium hypochlorite, excess of which is destroyed. Reaction of the bromate with excess bromide in acid solution, using a molybdenum catalyst, liberates bromine. This is allowed to react with rosaniline, which has been decolorized with acid. The color of the resulting bromo rosaniline is measured in the presence of tertiary butyl alcohol, using an absorptiometer. (auth)
