Twelve different extraction agents, based on the hydroxypyridinone (HOPO) chelating moieties 3,2‐HOPO, 3,4‐HOPO, and 1,2‐HOPO, have been synthesized and characterized for their ability to remove Pu(IV) from nitric acid solutions. Most of these,

Four new chelating hydroxypyridinone and catecholamide polystyrene-supported extractants have been prepared and evaluated for their ability to selectively remove pm levels of plutonium from a variety of acidic aqueous waste compositions. The hydroxyp

Extraction of Pu(IV) and Pu(VI) from nitric acid media by the promising new extractant l-hydroxy-6-N-octylcarboxamide-2(1H)-pyridinone (octyl-1,2-HOPO) has been investigated. The effects of nitric acid, sodium, aluminum and iron(III) nitrates on extr

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 spectrosc
