| titleOfInvention | Ruthenium separation method and apparatus |
| abstract | The present invention relates to a method and apparatus for trapping RuO 4 in an absorption solution by distillation to separate ruthenium in a purely high yield without interference of other elements. According to the present invention, a method of separating ruthenium by distilling RuO 4 from a ruthenium salt-containing solution, and a method of distilling ruthenium with RuO 4 from a ruthenium salt-containing sample and separating it by heating and distilling it at 85 ° C to 95 ° C for nitric acid. Obtaining RuO 4 from the reaction of the dissolved ruthenium and the H 5 IO 6 oxidant in the ruthenium-containing sample in a distillation solvent; And a ruthenium separation method comprising collecting the RuO 4 in an absorption solution. And ruthenium contained in the ruthenium from the sample to the method of separating by distillation with RuO 4, and evaporated and heated to 85 ℃ to 95 ℃ the RuO 4 by the reaction of the ruthenium-containing sample dissolved ruthenium with H 5 IO 6 oxidant of from nitric acid distillation solvent Obtaining; And introducing RuO 4 into an absorber including a mixed absorption solution of hydrochloric acid and hydrogen peroxide through a volatile gas discharge pipe and collecting the RuO 4 in a mixed absorption solution of hydrochloric acid and hydrogen peroxide. When 4 is introduced into the absorber, the discharge pipe is a ruthenium separation method is heated to 65 ℃ to 75 ℃; And a reaction vessel equipped with a volatile gas discharge pipe. A volatile gas absorber connected to the volatile gas discharge pipe and connected to the reaction vessel; A heating tape wound around the volatile gas discharge pipe; And an absorption solution inlet tube provided in the absorption cell of the volatile gas absorption device. According to the ruthenium separation method according to the present invention, ruthenium is recovered as ruthenium chloride in high recovery rate, specifically 95 wt% or more. In addition, recovery of ruthenium using the apparatus according to the present invention prevents the ingress of impurities such as water vapor, air, argon and / or other elements during the collection of RuO 4 absorbent solution. Therefore, in the absorber according to the present invention, RuO 4 collected in the absorbing solution can be directly quantified. Furthermore, ruthenium can be recovered as ruthenium chloride by heating and concentrating the absorption solution in which RuO 4 is collected. |
