| titleOfInvention | Separation method of platinum and ruthenium |
| abstract | (57) [Problem] To provide a method for achieving mutual separation of Pt and Ru by a simple extraction operation using a single extractant without volatilization. SOLUTION: The aqueous solution containing Pt and Ru has a hydrochloric acid concentration of 1%. Oxidation-reduction potential to 350 to 700 m After adjusting to V, Pt is selectively extracted with tributyl phosphate, or Pt and Ru are extracted by mixing tributyl phosphate with the aqueous solution whose hydrochloric acid concentration has been adjusted, and hydrochloric acid is mixed with the organic phase. The concentration of hydrochloric acid is adjusted to the above value, and the oxidation-reduction potential is adjusted to 350 to 500 mV, whereby Ru is back-extracted into the aqueous phase. By combining these two methods, Ru co-extracted from the organic phase from which Pt was extracted Can be back-extracted into the aqueous phase. |
