| Abstract: | A rapid method for the synergistic extraction and spectrophotometric determination of plutonium(VI) in milligram amounts using
a mixture of thenoyltrifluoroacetone (TTA) and tributyl phosphate (TBP) in benzene has been developed. Quantitative extraction
is obtained from aqueous solutions of pH=2 affording separation from many commonly occurring impurities, viz., thorium, fission
products and cladding materials. The precision and accuracy of the method has been found to be∼1%. The study of the solid
product isolated from the extraction system indicates the stoichiometry of the extracted species as PuO2(TTA)2 TBP. |
