Solvent extraction is a technology used to recycle platinum group metals (PGMs), which are classed as critical materials because of their importance in UK manufacturing. It is one of the more sustainable and efficient processes in PGM recycling, and can be used commercially to separate all PGMs except rhodium. To purify rhodium, most PGM recyclers depend on unsustainable and energy intensive precipitation/calcination processes which do not allow for ligand recycling. Recent work in the Love and Morrison labs discovered that a combination of two simple extractants, neither of which will extract rhodium on its own, can result in the synergistic recovery of rhodium by solvent extraction.

溶剂萃取是一种用于回收铂族金属（PGMs）的技术，由于其在英国制造业中的重要性而被列为关键材料。它是PGM回收中更可持续和有效的方法之一，并且可以在商业上用于分离除铑之外的所有PGM。为了纯化铑，大多数PGM再循环器依赖于不可持续的和能量密集的沉淀/煅烧工艺，其不允许配体再循环。Love和莫里森实验室最近的工作发现，两种简单的萃取剂的组合，这两种萃取剂都不会单独萃取铑，可以通过溶剂萃取协同回收铑。
