Solvent extraction of zirconium(IV) and uranium(VI) from chloride media with bidentate Schiff bases
The systematic liquid-liquid extraction behavior of zirconium(IV) and uranium(VI) with bidentate Schiff bases (HSB) in benzene as the diluent has been studied. Quantitative extraction of zirconium(IV) has been achieved. Four consecutive extractions are, however, necessary for quantitative extraction of uranium(VI) at pH 6.0. The extracted species seem to be (Zr/sub 4/(OH)/sub 8/(H/sub 2/O)/sub 4/(HSB)/sub 6/)Cl/sub 8/ and ((UO/sub 2/)/sub 2/(OH)/sub 2/(HSB))Cl/sub 2/. The extraction efficiency is in the order: Zr/sup 4 +/ > Th/sup 4 +/ > UO/sub 2//sup 2 +/. It is possible to separate zirconium from thorium and uranium by solvent extraction with HSB. Exchange reaction technique has been employed for separation of thorium and uranium. 19 references, 3 figures, 1 table.
