Impact of uranium carbide organics treated by prolonged boiling and electrochemical oxidation upon uranium and plutonium solvent extraction

, 2017
The dissolution of uranium or uranium-plutonium carbide fuel in nitric acid leads to ~50% carbon evolved as carbon dioxide, the remainder remains in the solution as soluble organics. These dissolved organic molecules interfere with the solvent extraction

Solvent Extraction of Uranium Using Alkylamines

Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1963
The new conversion refining process using high molecular weight alkylamines was developed in order to obtain directly highly purified UF4 or UO3 from ore leaching solution without the precipitation process of yellow cake. Suitable conditions for each of the extraction, conversion and stripping process were described, and also the flow diagram of this ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, Volume 41, Issue 7, Page 459-469, July 2026.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.
