Photoisomerization-mediated tunable pore size in metal organic frameworks for U(VI)/V(V) selective separation

Nature Communications
Selective extracting uranium from seawater is quite challenging, particularly the presence of vanadium, which poses a significant obstacle for most amidoxime absorbents.

A New Comprehensive Model to Simulate and Optimize Fluid Flow in Complex Well‐Formation System for In Situ Leaching Uranium

Energy Science & Engineering
In situ leaching (ISL) is an important method for green and efficient development of sandstone‐type uranium ore. It achieves ISL of uranium through the deployment of injection and extraction vertical well patterns.

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 ...

Enhancement of Extraction of Uranium from Seawater

, 2016
Even at a concentration of 3 μg/L, the world’s oceans contain a thousand times more uranium than currently know terrestrial sources. In order to take advantage of this stockpile, methods and materials must be developed to extract it efficiently, a difficult task considering the very low concentration of the element and the competition for extraction by

Sequencing of the rus gene before and after the mutation with DES in the bacterial Acidithiobacillus sp. FJ2

یافته‌های نوین در علوم زیستی, 2019
In Acidithiobacillus ferrooxidans, the proteins present in the electron transfer pathway cause ferrous iron oxidation which leads to uranium extraction. The relationship between gene sequence and uranium extraction has not been investigated yet. Based on

To the question of the intensification of the processes of uranium extraction from refractory raw materials

Metalurgija, 2019
Recently, one of the main directions for increasing the extraction of uranium from difficult-to-hide ores is the use of intensifiers, which allow the most complete transfer of uranium from one valence state to another. In the article, the catalyst “M-1”,
