Uranium (U) is of enormous global importance because of its use in energy generation,
albeit with potential environmental legacies. While naturally occurring U is widespread in the …

Environmental contamination caused by radionuclides, in particular by uranium and its
decay products is a serious problem worldwide. The development of nuclear science and …

The crystal structures of uranyl minerals and inorganic uranyl compounds are important for
understanding the genesis of U deposits, the interaction of U mine and mill tailings with the …

In oxidizing environments, the toxic and radioactive element uranium (U) is most soluble and
mobile in the hexavalent oxidation state. Sorption of U (VI) on Fe-oxides minerals (such as …

Uranium phytoextraction, the use of plants to extract U from contaminated soils, is an
emerging technology. We report on the development of this technology for the cleanup of U …

Reduction and oxidation measurements create important data for analysis of wet soils.
These measurements are actually recordings of voltage (EH) over time between a reference …

By 1911, the atomic weight of uranium had been refined to 238.5 (Gmelin, vol. A2, 1980a).
The natural isotope 235 U was discovered in 1935 by mass spectrometry. The artificial …

The solubility of uranyl minerals controls the transport and distribution of uranium in many
oxidizing environments. Uranyl minerals form as secondary phases within uranium deposits …

Uranium may present in soil as precipitated, sorbed, complexed, and reduced forms, which
impact its mobility and fate in the subsurface soil environment. In this study, a uranium …

Reaction of aqueous uranium (VI) with iron (II) monosulfide mackinawite in an O2 and CO2
free model system was studied by batch uptake measurements, equilibrium modeling, and L …
