Solvent extraction, also called liquid-liquid extraction or partitioning, is a procedure used to separate compounds based on their solubility in two immiscible liquids, usually water and an organic solvent. During solvent extraction, one or more of the solutes in one of the liquid phases migrates to the other liquid phase.
