Abstract: Phenanthraquinone monothiosemicarbazone (PTS) has been used in the determination of ruthenium by spectrophotometric method. PTS forms a green complex with ruthenium (III ) at pH 5.2 to 6.7. The complex is soluble in DMF. The maximum absorbance of the complex has been found at 660 nm. The complex has been found to obey Beers Law up to 9.38 ppm. Effect of diverse ions in the determination of ruthenium has also been studied. Attempts have been made to mask the various interfering cations by anions. The sensitivity of the method is 0.0102 µg Ru/cm2 at 660 nm

Keywords: DMF, Phenanthraquinone monothiosemicarbazone (PTS), ruthenium (III), spectrophotometric
