Summary

Flotation-Spectrophotometric Determination of Ruthenium in the Ru(lV)-Chloride-Rhodamine 6G-Toluene System

The reduction of RuO4 in hydrochloric acid has been examined. A sensitive flotation-spectrophotometric method of the determination of ruthenium based on the ion associate formed by the anionic chloride complex of ruthenium RuCl6 2− with the basic dye Rhodamine 6G (R6G) has been developed. The solution of the ion associate obeys Beer's law up to the concentration of 0.25μg Ru/ml. The ion associate precipitates when the aqueous solution is shaken with toluene. The separated compound is dissolved in acetone. The molar absorptivity (ε) at 530 nm is 5.1×105 1·mole−1-cm−1. The relative standard deviation is 3–7%. The mole ratio of Ru∶R6G in the complex is 1∶5. Osmium reacts similarly. The determination of ruthenium can be selective after the preliminary separation of osmium as OsO4. The method was applied to the determination of microgram amounts of ruthenium in crucible platinum.
