Kinetic ruthenium and iridium determination in industrial sulfate solutions
This paper proposes a procedure for kinetic ruthenium and iridium determination in sulfate solutions without their separation from each other and from their element associates. Ruthenium was determined by the indicator Tropaeolin 00 oxidation by potassium periodate and iridium, by oxidation of mercury with cerium in the presence of perchloric acid. Various methods of treatment of samples of industrial solutions for converting ruthenium and iridium into the needed catalytically active form were studied: evaporation concentration with hydrochloric and sulfuric acids, boiling with a mixture of hydrochloric acid and hydrogen peroxide, fusion of a dried sample with sodium peroxide, and dissolution of the fused mass in acids. The proposed procedure makes it possible to significantly accelerate express ruthenium and iridium determination in sulfate solutions from a single sample without separating them from each other and from the associated elements.
