Spectrophotometric determination of Ru(III) using rhodanine

Abstract

1019-1020A simple and direct spectrophotometric method using 2-thion-thiazolid-4-one has been developed for determination of Ru (III).Molar absorptivity and Sandell' s sensitivity are calculated to be 6.5555×103 L mol-1 cm-1 and 0.0154 μg cm-2 respectively. The effect of various parameters including time, pH and volume of reagent has been studied. The Beer's law is obeyed over the range 0.202-6.873 μg of Ru(III). The method has been applied for the determination of Ru(III) in various synthetic and real samples
