Abstract

A method of spectrophotometric analysis for ruthenium, using the reagent 1-pentyl 4,6-dihydroxy-5-nitrosopyridine-3-carboxylate, has been developed. Several interferences are removed by extraction prior to the developemnt of the purple color formed between PDNHPC and ruthenium. The molar absorptivity of the PDHNPC-ruthenium complex is 4.2×104 at 535 nm. The complex forms at a 3∶1 ligand-metal ratio. This procedure provides the most sensitive colorimetric method for the determination of ruthenium.
