Abstract
Addressing the challenge of recovering precious metals from petrochemical waste catalysts,the complete process of"oxidation roasting-mechanical activation-synergistic leaching"is developed.By optimizing the pretreatment conditions and leaching parameters,efficient selective leaching of platinum and palladium is achieved in a mild system,while suppressing carrier dissolution,ultimately,the high-purity platinum and palladium powders are obtained through ion exchange and reduction.This process provides a feasible path for the green resource utilization of waste catalysts.关键词
