　　Liquid-liquid extraction (LLE), also called solvent extraction (SX), is a process that allows the separation of two or more components due to their unequal solubilities in two immiscible liquid phases.The high prices of precious metals like platinum group metals (PGMs) have ensured that there is continued interest in the development of new extractants for the commercial concentration and separation of these metals.
