Separation at Platinum Group Metals(PGMs) is relevant to treatment in high level wastes. But some PGMs are so inert that their extraction is not always efficient. In this study, we investigated how to accelerate solvent extraction of inert PGMs under temperature controlled condition. Here in, we employed a pyridine diamide as an extractant.
