Achieving efficient uranium extraction by in situ ultrasonic texturization of commercial Fe powder

Abstract

The widespread presence of fluorinated nuclear effluent (F-) in the nuclear fuel cycle encourages the efficient extraction of hexavalent uranium (U(VI)) under the interference of F-. Nano zero-valent iron (n-ZVI)...

Enhancing Commercially Iron Powder Electron Transport by Surface Biosulfuration to Achieve Uranium Extraction from Uranium Ore Wastewater

“…Nano zero-valent iron (nZVI) is widely used in the remediation of contaminated groundwater due to its high reactivity and large specific surface area. − nZVI has shown superior performance in solving environmental problems such as organic matter and heavy metal pollution. However, its practical application has been hindered due to the tendency to agglomerate, oxidize, and passivate during storage and in situ repair processes. , Commercial zero-valent iron powder (ZVI) is regarded as an ideal substitute for nZVI due to its similar composition, low price, easy availability, safety, and environmental protection, and other advantages . Many methods have been reported for modifying ZVI, such as chemical modification, physical modification, biological modification, etc.…”
