摘要：
Ruthenium(III) forms a brownish yellow coloured water soluble complex with cinnamaldehyde isonicotinoylhydrazone (CINH) reagent in acidic buffer pH 3.0 with lambda(max) at 402 nm. The molar absorpitivity and Sandell's sensitivity is 1.25 x 10(4) L mol(-1) cm(-1) and 0,00809 mu g/cm(2), respectively. The Beers law validity range is 0.202 to 4.04 mu g/mL. Ruthenium(III) forms (M:L) 1: 1 complex with CINH and stability constant of the complex is 4.56 x 10(5). The developed derivative spectrophotomrtic method was employed for the determination of ruthenium(III) in synthetic samples of alloy and river water samples. The effect of various diverse ions have also been studied.
