The PUREX process was invented by Herbert H. Anderson and Larned B. Asprey at the Metallurgical Laboratory at the University of Chicago, as part of the Manhattan Project under Glenn T. Seaborg; their patent "Solvent Extraction Process for Plutonium" filed in 1947, [14] mentions tributyl phosphate as the major reactant which accomplishes the ...
Purex is a brand of laundry detergent and laundry-related products manufactured by Henkel North American Consumer Goods and marketed in the United States and Canada. Purex is one of the most widely used laundry detergents in North America. Its original product, Purex Bleach, was a major competitor to Clorox bleach.
Herbert H. Anderson (1913 – 2001) [1] [2] was an American organic chemist, a member of Glenn Seaborg's Met Lab group at Chicago during the Manhattan Project. [3] Anderson was a co-inventor, with Larned B. Asprey, of the PUREX process for plutonium and uranium extraction.
Notable brands of these packs include All, Arm & Hammer, Gain, Purex, Persil, Rinso and Tide. [1] They first became popular in February 2012 when they were introduced by Procter & Gamble as Tide Pods (Ariel Pods in Europe). [1] The chemistry of laundry detergent packs is the same as in liquid detergents (including alkylbenzenesulfonates).
The UREX process is a PUREX process which has been modified to prevent the plutonium being extracted. This can be done by adding a plutonium reductant before the first metal extraction step. In the UREX process, ~99.9% of the uranium and >95% of technetium are separated from each other and the other fission products and actinides. The key is ...
It is also used in nuclear reprocessing as part of the PUREX process. A 15–40% (usually about 30%) solution of tributyl phosphate in kerosene or dodecane is used in the liquid–liquid extraction (solvent extraction) of uranium, plutonium, and thorium from spent uranium nuclear fuel rods dissolved in nitric acid. Liquid extraction can also be ...
It is possible, however, to remove the americium from the plutonium by a chemical separation process. Even under the worst conditions, the americium/plutonium mixture is less radioactive than a spent-fuel dissolution liquor, so it should be relatively straightforward to recover the plutonium by PUREX or another aqueous reprocessing method.
