PUREX (plutonium uranium reduction extraction) is a chemical method used to purify fuel for nuclear reactors or nuclear weapons. [7] PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel (spent nuclear fuel, or irradiated nuclear fuel).
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 ...

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. The brand name is also used for a line of in-wash "fragrance booster" products called Purex Crystals. The Purex Crystals brand was originally launched as an in-wash fabric softener product.
Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Red oil is defined as a substance of varying composition formed when an organic solution, typically tri-n-butyl phosphate (TBP, an agent used for extracting heavy metals in nuclear reprocessing plants) and its diluent, comes in contact with concentrated nitric acid at a temperature above 120 °C.
The Enciclopedia Libre was founded by contributors to the Spanish Wikipedia who decided to start an independent project. Led by Edgar Enyedy, they left Wikipedia on 26 February 2002, and created the new website, provided by the University of Seville for free, with the freely licensed articles of the Spanish Wikipedia.
