Extraction of Plutonium from Uranium-Plutonium Alloy with Uranium Trichloride
Nuclear Applications, 1967The reaction UCl3 + Pu ⇋ PuCl3 + U was examined by measurement of the redistribution of plutonium after equilibration of molten uranium alloys containing 0.2 to 4.2% Pu with UCl3 diluted with CaCl2...

Extractive spectrophotometric determination of uranium with Malachite Green
Talanta, 1977A sensitive spectrophotometric method based on the extraction of a uranium-benzoate-Malachite Green complex by chlorobenzene is described. The absorption maximum is at 635 nm and the molar absorptivity is 8.3 x 10(4) 1 mole(-1), cm(-1). A preliminary separation of uranium by extraction with methyl isobutyl ketone from acid-deficient aluminium nitrate ...

Extracting Uranium From Seawater
Chemical & Engineering News Archive, 2012If, like most scientists, you haven’t thought much about the composition of seawater, it may come as a surprise that the oceans contain uranium. In fact, they hold a staggering quantity of the heavy element. “It’s estimated that more than 4 billion metric tons of uranium are dissolved in the Earth’s oceans,” according to Benjamin P.

Selective extraction of uranium from uranium–beryllium ore by acid leaching
Journal of Radioanalytical and Nuclear Chemistry, 2019Both uranium and beryllium are very important strategic metals and have been applied to many fields, such as nuclear industries, atomic energy, metallurgical industries and telecommunications industries. When uranium and beryllium in the ore were leached simultaneously, a complicated downstream separation process was needed.

Journal of Dispersion Science and Technology, 2014
The leach liquor (0.5 g/L Mo, 0.05 g/L U) obtained from the leaching process of molybdenum-uranium ore material was treated using solvent extraction to recover U(VI) by LIX 622N, which is a salicylaldoxime derivative. The influence of various basic variables such as pH, concentration of LIX 622N, temperature, different stripping reagents, phase ratio ...

Uranium extraction by complexation with siderophores
2016One of the major concerns of energy production is the environmental impact associated with the extraction of natural resources. Nuclear energy fuel is obtained from uranium, an abundant and naturally occurring element in the environment, but the currently used techniques for uranium extraction leave either a significant fingerprint (open pit mines) or ...

Challenges of photocatalytic extraction of uranium: a review
Chemical SynthesisNuclear energy, known for its low carbon emissions and high energy density, is considered one of the most promising future energy sources. However, the generation of nuclear waste and depletion of uranium resources make the development of simple, efficient, and cost-effective uranium extraction methods critical for the sustainable development of ...
