Liquid–liquid extraction - Wikipedia

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Extraction (chemistry) - Wikipedia

Extraction in chemistry is a separation process consisting in the separation of a substance from a matrix.Common examples include liquid-liquid extraction, and solid phase extraction.The distribution of a solute between two phases is an equilibrium condition described by partition theory.
