preparation of uranium/uranyl sulfates
Can anybody suggest a process for the preparation of uranyl sulfate and/or uranium sulfate from the metal?

| Quote: | | Sulfurlc acid-hydrogen peroxide mixtures react slowly with the metal. at 75°C forming uranyl sulfate.— The addition of small amounts of chloride or
fluoride to H2S04 - H202 mixtures increases the dissolution rate. |
From a LANL paper which referenced:
R. P. Larson, Anal. Chem. 31, 545 (1959)
Dissolution of Uranium Metal and its Alloys.

Perhaps someone with full access can retrieve the Anal. Chem. paper for details.

@ not_important & pantone159,
Thanks for the abstract and paper. The processes described appear to be quite manageable.

I just posted the 138 page Chapter LXIII on Uranium from Volume XII of Mellor's "A Comprehensive Treatise on Inorganic and Theoretical Chemistry", it
is in the New Books (Inorganic Chemistry) forum in References.
The section on uranium sulfates is attached.

@ Sauron,
Thanks for the excerpt. It is fascinating how much fundamental work from the past two centuries is out there in scanned literature that is apparently
inaccessible by keyword searches. I will contact you regarding access to the References section.

You can't really expect keyword searches to do everything.
Just as regards Mellor's 16 volumes, until a few weeks ago, only volumes 1, 2, 8, amd half of 10 plus a lone chapter from 11 were scanned and on the
Net at all, mostly through one of our members S.C. Wack. Then some damn fool (me) decided to scan the rest of it and I am pleased to say the end is
near. Then there are 8 supplements to attack. But those are concerned only with the halogens, alkali metals, N, P and B.
