Re: RE: uranium nitrate disposal
Mr. M.Kirby at S.A.I.M.R in Johannesburg, South Africa asks:
>>Uranium nitrate in solution. How do you guys dispose of the stuff?
I've got 20 litre drums of the stuff sitting in my waste store and would
appreciate any advice.<<
Uranyl ion can be precipitated out, very nearly quantitatively, as sodium
uranyl sulfate, a dense granular bright yellow precipitate easily separated
out and stored in an airtight jar. I suppose you have some idea of the
initial concentration of the solutions. From then on it's a straightforward
stoichiometric calculation of how much sodium sulfate (or sodium hydroxide
and sulfuric acid) you need. - In the United States I doubt you could find
anyone in a hospital who could do the calculation, and - if I didn't do it
myself - I would enlist the aid of a bright high school chemistry student.
Obviously incineration would only disperse the stuff, since you're disposing
of a chemical element.
