| titleOfInvention | Method for recovering palladium from selenium powder containing palladium |
| abstract | PROBLEM TO BE SOLVED: To provide a method for selectively separating and recovering palladium from selenium powder containing palladium. SOLUTION: By adding hydrochloric acid and an oxidizing agent to selenium powder containing palladium, the selenium powder containing palladium is dissolved at a liquid temperature of 55 ° C. or less (dissolution step), and dihexyl sulfide is dissolved in the obtained solution. Is preferably contacted with an organic solvent containing 20 to 25% by volume, and only palladium is extracted into the organic solvent (extraction process), and ammonia water is contacted with the organic solvent from which palladium has been extracted, and palladium is back-extracted into the aqueous phase. (Back extraction process) By separating, selenium powder and palladium are collected. [Selection figure] None |
