Extractive spectrophotometric determination of vanadium as vanadium (III) -thenoyltrifluoroacetone complex

Using 2-theonyltrifluoroacetone (HTTA) as a reagent, analytical studies have been carried out on vanadium but most of the vanadium extractions reported are based on vanadium(V) or vanadium(IV). The vanadium(III)-TTA complex has not been studied for its analytical applications. The proposed method makes use of the extraction of VIII-TTA complex into benzene for the determination of vanadium. The studies involving optimisation of conditions, stoichiometry of the complex, interference of foreign ions and applicability to synthetic and natural samples have been carried out and the results are reported.
