Spectrophotometric Extraction Methods Specific for Uranium

Analytical Chemistry, 1959
Two spectrophotometric extraction methods specific for uranium are described. Uranium as tetrapropylammonium uranyl trintrate is quantitatively separated from large quantities of diverse ions by extraction into methyl isobutyl ketone (4-methyl-2-penthnone) from an acid-deficient aluminum nitrate salting solution.

Uranium extraction by complexation with siderophores

2016
One 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 ...
