Abstract
An investigation has been made to determine the applicability of the osmate-naphthylamine reaction to the ruthenate system. It was found that under proper conditions. ruthenium (RuVI) reacts with 1-naphthylamine-3,5.7-trisulfonic acid to form a water-soluble red complex ion with a maximum absorbance at 530 mμ. The complex was found to be stable and to obey Beer's law over a concetration range of 0.5 to 14 p.p.m. The effects of PH, reagent concentration, and diverse 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 has been developed.
