Abstract
The systematic licuid-liquid extraction behaviour of zlrconium(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 [Zr4(OH)8(H2O)4(HSB)6]Cl8and [(UO2)2(OH)2(HSB)[Cl2.The extraction efficiency is in the order : Zr4+> Th4+UO2 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.Keywords
