Spectrophotometric determination of uranium in process streams of a uranium extraction plant

Talanta, 1997
This paper deals with the development and standardization of procedures for the determination of uranium on a routine basis in various process streams of a uranium extraction plant, covering a wide range of concentrations from 350 g 1(-1) down to 5 mg 1(-1) using only a spectrophotometric technique.

Extraction chromatography of uranium with dioctyl sulphoxide

Talanta, 1970
Uranium(VI) is quantitatively extracted from aqueous perchlorate media into dioctyl sulphoxide in 1,2-dichloroethane. The extracted species contains four sulphoxides for each uranium. Most other metal ions are not appreciably extracted. On columns containing a solid support impregnated with dioctyl sulphoxide in 1,2-dichloroethane, uranium(VI) may be ...

Uranium Extraction from Seawater via Hydrogen Bond Porous Organic Cages.

Journal of the American Chemical Society
Uranium (U), a high-performing, low-emission energy source, is driving sustainable economic growth. Herein, we synthesized two crystalline phases (HPOC-α and β) by an unreported amidoxime organic cage used for uranium capture.

Bacteria in uranium extraction

Physics Bulletin, 1977
Forecasts of uranium demand up to the end of the century need to be revised constantly because of the uncertainty at present over the rate of development of nuclear power. But even the requirements of nuclear power stations which have already been built or are under construction are going to make heavy demands on the uranium producing industry.
