METHOD FOR REMOVING RUTHENIUM IN THE PRESENCE OF RHODIUM, PALLADIUM, AND NON-FERROUS METALS IN ELECTROLYTE

摘要

The proposed method for removing ruthenium in the presence of rhodium, palladium, and non-ferrous metals in electrolyte consists in producing complex chemical compounds of the said metals with organic reagents, consequently isolating compounds of palladium, color metals, and ruthenium by extraction using organic solvent, measuring the optical density of the extracts and determining the content of ruthenium by the data on the optical density. As the organic regent for producing ruthenium compounds, salicylic baldheaded hydrazones is used. To the reaction medium, alkaline dye with maximal absorption of optical radiation in the 540 ... 585 nm wavelength ranges is added. Ruthenium is isolated as ion associate.
