Spectrophotometric determination of ru(iv) using 5-hydroxyimino-4-imino-1,3-thiazolidin-2-one as a novel analytical reagent

Abstract
The interaction of Ru(IV) ions with a novel analytical reagent – 5-hydroxyimino-4-imino-1,3-thiazolidin-2-one, by spectrophotometric method was investigated. The complex is formed at pH 5.0 in acetate buffer medium after heating in the boiling water bath (~371 K) for 25 min. The complex has maximum absorption at 350 nm and is stable for 24 h. Beer’s law is valid over the concentration range of 0.5–6.1 µg mL–1 for Ru(IV). The molar absorptivity at λ = 350 nm is 6.21 × 103 L mol–1 cm–1. The limit of detection of this method is 0.2 µg mL–1. The interfering effect of various cations and anions on the spectrophotometric determination of the Ru(IV) were investigated. The proposed method was successfully applied to the determination of Ru(IV) in alloys.
