The extraction of uranium by amidoximated orlon

Talanta, 1997
The nitrile groups in polyacrylonitrile (Orlontrade mark) fabric were converted to amidoxime groups to produce an amidoximated orlon fabric. The amidoximated fabric was evaluated for its ability to extract uranium from aqueous solution with a wide range of temperature and pH values.

OSCILLATORY EXTRACTION OF URANIUM

Solvent Extraction and Ion Exchange, 1998
The kinetics of U and Ce extraction by tri-n-butyl-phosphate (TBP) and the redox potential behavior in the aqueous phase have been investigated in an oscillatory extraction system. The extraction has been followed continuously by UV-visible spectroscopy, potentiometry, and radioactive counting methods.

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 ...

On microfluidic solvent extraction of uranium

Chemical Engineering and Processing - Process Intensification, 2018
Abstract This experimental study is focused on several aspects of microfluidic solvent extraction of uranium in setups comprising of microbore tube(s) connected to microfluidic junction(s). Extraction experiments are carried out using simulated lean aqueous phase having 550 ppm uranium in 1 M HNO3 as the feed.
