Liquidliquid extraction

Liquidliquid 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.
