Substoichiometric determination of uranium in phosphate rock

Abstract

The substoichiometric isotope dilution analysis for U(VI) in a synergic extraction system of an excess amount of a chelating agent hexafluoroacetylacetone (HHFA) and a substoichiometric amount of U(VI) can be precisely extracted, and U down to ppm levels can be accurately determined by the present method. This method was applied to the analysis of a phosphate rock.
