METHOD FOR RECOVERING PALLADIUM |
摘要 |
PROBLEM TO BE SOLVED: To efficiently recover palladium at a high recovery from a palladium-containing waste liquid in which an inorganic sulfur oxide such as sodium sulfite is included without requiring a complicated operation.SOLUTION: The method for recovering palladium comprises: a step of controlling the pH of a palladium-containing aqueous solution comprising an inorganic sulfur oxide to 2 or less; a step of adding a reducing agent to the palladium-containing aqueous solution to reduce palladium; and a step of adding a cationic surfactant to the palladium-containing aqueous solution and flocculating and depositing the reduced palladium to recover palladium. |
