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
