Rapid extraction and spectrophotometric determination of vanadium(IV) with thiothenoyltrifluoroacetone.

Abstract

Thiothenoyltrifluoroacetone in carbon tetrachloride-butanol (1:1) is used for extraction and spectrophotometric determination of vanadium (IV) at pH 4.5-5. The greenish-yellow complex is measured spectrophotometrically at 450 nm. The system conforms to Beer's law over the range 2-11 mug/ml of extract. The colour of the complex is stable for at least 80 hr… (More)
