An investigation was made to determine the applicability of the osmate -- naphthylamine reaction to the ruthenate system. It was found that under proper conditions, ruthenium (Ru VI) reacts with 1-naphthylamine3,5,7-trisulfonic acid to form a water-soluble red com plex ion with a maximum absorbance at 530 m mu . The complex was found to be stable and to obey Beer's law over a concentration range of 0.5 to 14 ppm. The effects of pH, reagent concentration, and diwerse ions were studied. The nature of the complex in solution was investigated, and a standard procedure for analysis recommended. A procedure for the removal of ruthenium from all interfering materials was developed based on well known distillation techniques. A rapid, sensitive, reproducible, and accurate method for the spectrophotometric determination of ruthenium was developed. (auth)
