Progress and Challenges of Materials and Methods for Uranium Extraction From Seawater

open access: yesHe huaxue yu fangshe huaxue, 2023
The ocean covers 70% of the earth’s area, and the seawater uranium is more than 1000 times that of terrestrial uranium ore. In order to increase the power generation and ensure the sustainable operation of nuclear power plants, the development of ...

Removal of chromium (III) by two-aqueous phases extraction [PDF]

open access: yes, 2009
Two-aqueous phase extraction of chromium (III) as a solute from their aqueous solutions was investigated using polyethoxylated alcohols (CiEj) as a biodegradable non-ionic surfactant in the presence of anionic sodium dodecylbenzene sulfonate (SDBS ...

Fluorometric Microdetermination of Uranium. II. Extraction of Uranium [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1950
Abstract A minute amount of uranium suitable for the fluorometric method of determination is effectively precipitated from the solution together with hydrous ferric oxide as co-precipitator. The efficiency of co-precipitation seems to be nearly perfect for the purpose, and the adsorption and the digestion effect were observed in ...

Metal-Half-Salen Chemistry for One-Pot Mineralization on Hydrophobic Polymer Membranes. [PDF]

open access: yesAdv Sci (Weinh)
Here we report a versatile one‐pot synthetic strategy for organic–inorganic composite membranes, which leverages a metal half‐Salen system to precisely govern the competing kinetics of coordination and hydrolysis. In contrast to conventional two‐step metal‐phenol chemistries, our integrated approach substantially simplifies the fabrication process ...

Uranium from phosphoric acid: Kinetic studies of the solvent extraction processes for uranium extraction

open access: yesDesalination and Water Treatment, 2009
Kinetics of the mass transfer processes involved in uranium recovery from wet process phosphoric acid (WPA) by solvent extraction employing synergistic extractants has been studied. In the present investigation results on the kinetics of separation of entrained solvent by diluent washing and uranium mass transfer behaviour have been discussed.

Uranium extraction with modified sorbents

open access: yesKompleksnoe Ispolʹzovanie Mineralʹnogo syrʹâ/Complex Use of Mineral Resources/Mineraldik Shikisattardy Keshendi Paidalanu, 2020
Hydrometallurgical processing of uranium-containing raw materials generates a significant amount of liquid industry-related waste, namely waste solutions that require disposal. Sorption is known as one of the most effective methods for purifying liquid matters contaminated with radionuclides.
