ABSTRACT:
Ruthenium (III) forms a purple Coloured water soluble complex with Diacetyl Monoxime Isonicotinoylhydrazone (DMIH) reagent in acidic buffer PH 4.5 with ? max at 346 nm. The molar absorptivity and sandell’s sensitivity are 1.4 X 10 4 L mol –1 cm -1 and 0.0048 µg / cm 2 respectively. The Beer’s law validity range is 0.505 to 6.06 µg / mL. Ruthenium (III) forms (M: L) 1:1 complex with DMIH and stability constant of the complex is 2.694 X 10 6 .The derivative spectrophotometric determination of Ru (III) was carried out by measuring peak height method. The developed derivative spectrophotometric method was employed for the determination of Ruthenium (III) in synthetic samples of alloy and river water samples .The effect of various diverse ions was also studied.
