Abstract: Reactions of N′-hydroxy-1,2,5-oxadiazole-3-carboximidamide with SeO₂ or thiourea afford complex materials containing elements of the reactants and diselenide or disulfide bridges, respectively. These materials were tested as agents for Uvi extraction from liquid media in the range of pH 6–9 including technological and sea water.

Keywords: uranium, amidoximes, sorption, 1,2,5-oxadiazoles, diselenides, disulfides, polymerization.
