| Abstract: |
| Platinum group metals (PGMs) are strategic metals that are in extremely short supply in China, and their recycling is an important way to practice the strategy of resource security and carbon peaking and carbon neutrality. Separation and purification of PGMs are important components of their recycling. However, due to the similar properties, separation and purification are difficult, which seriously restrict the sustainable development of PGMs industry. Therefore, the latest separation and purification technologies of PGMs were comprehensively reviewed, with emphasis on the principle and application of solvent extraction and ionic liquid extraction, and the restriction conditions and development trend of extraction separation of PGMs were analyzed, which provides research ideas and technical support for PGMs separation and purification in the future. |
