Spectrophotometric Determination of Ruthenium Utilizing its Catalytic Activity on Oxidation of Hexacyanoferrate(II) by Periodate Ion in Water Samples

The catalytic effect of ruthenium chloride on the outer sphere electron transfer of hexacyanoferrate(II) by periodate ion in aqueous alkaline medium has been effectively employed to determine ruthenium(III) at micro level. The optimum reaction condition has been established and fixed time procedure is adopted. A linear relationship between changes in absorbance and added Ru(III) concentration has been utilized for the trace level determination of Ru(III).
