Abstract  

When annealing the evaporation residue formed by evaporating a solution containing ruthenium, phosphates and nitrates, ruthenium volatilizes. The amount of volatilized ruthenium (both106Ru traces and milligram amuonts of Ru) depends on the solution composition before evaporation and on the temperature and time of annealing. Volatility occurs at a temperature as low as 300°C. We suppose that the volatility is due to thermal decomposition of the ruthenium compounds with phosphates. The released atoms of ruthenium are oxidized by the decomposition products of the nitrate. The formation of complex compounds of ruthenium with phosphates during the evaporation of the solution follows from the data of elemental and spectral analysis and ion exchange chromatography.

Abstract  

Volatilization behaviour of ruthenium from boiling solutions has been studied using106Ru-labeled (Na2 RuNO(NO2)4OH). The volatilization rate of ruthenium was measured at a constant concentration of nitrate in various acidities using a mixture of nitric acid and sodium nitrate. Volatilization of ruthenium was found to accur after a certain induction period depending on the acidity. However, the volatilization rate was constant at acidities greater than 3M in the presence of 10M nitrate. Ruthenium volatilized from a mixture of nitric acid and sulfuric acid, but the volatilization rate and induction period were independent of the mixing ratio of both acids.
