Uranyl acetate is the acetate salt of uranium oxide, a toxic yellow-green powder useful in certain laboratory tests. Structurally, it is a coordination polymer with formula UO 2 (CH 3 CO 2 ) 2 (H 2 O)·H 2 O.
The accident involved waste from the sodium uranyl acetate process used by the early Soviet nuclear industry to recover plutonium from irradiated fuel. [13] The acetate process was a special process never used in the West; the idea is to dissolve the fuel in nitric acid, alter the oxidation state of the plutonium, and then add acetic acid and ...
The sodium uranyl acetate process was used by the early Soviet nuclear industry to recover plutonium from irradiated fuel. [34] It was never used in the West; the idea is to dissolve the fuel in nitric acid, alter the oxidation state of the plutonium, and then add acetic acid and base. This would convert the uranium and plutonium into a solid ...
Depleted uranium was originally stored as an unusable waste product (uranium hexafluoride) in the hope that improved enrichment processes could extract additional quantities of the fissionable 235 U isotope. This re-enrichment recovery of the residual uranium-235 is now in practice in some parts of the world; e.g. in 1996 over 6000 metric ...
Bioremediation of radioactive waste or bioremediation of radionuclides is an application of bioremediation based on the use of biological agents bacteria, plants and fungi (natural or genetically modified) to catalyze chemical reactions that allow the decontamination of sites affected by radionuclides.

2 ion represents the uranium(VI) state and is known to form compounds such as uranyl carbonate, uranyl chloride and uranyl sulfate. UO 2+ 2 also forms complexes with various organic chelating agents, the most commonly encountered of which is uranyl acetate .
2 also forms complexes with various organic chelating agents, the most commonly encountered of which is uranyl acetate. [105] Unlike the uranyl salts of uranium and polyatomic ion uranium-oxide cationic forms, the uranates, salts containing a polyatomic uranium-oxide anion, are generally not water-soluble.
Another method is the thermal decomposition of a complex, such as an acetate complex. For example, microcrystalline barium diuranate, BaU 2 O 7, was made by thermal decomposition of barium uranyl acetate at 900 °C. [4] Ba[UO 2 (ac) 3] 2 → BaU 2 O 7... (ac=CH 3 CO 2 −) Uranates can be prepared by adding alkali to an aqueous solution of a ...
