Conditions for the spectrophotometric determination of ruthenium as perruthenate have been established. Stable solutions of perruthenate are obtained only when the tetroxide is distilled into dilute sodium hydroxide (1M) containing hypochlorite. At higher hydroxide concentrations (6M) perruthenate is reduced rapidly by water to ruthenate even in the presence of hypochlorite. From 200 to 400 gamma of ruthenium can be determined to an accuracy of +2% at the 95% confldence level. An improved procedure for the distillation of ruthenium tetroxide which is particularly rapid and clean uses a slurry of sodium bismuthate in dilute sulfuric acid as the oxidant. (auth)
