solvent extraction - an overview | ScienceDirect Topics
solvent extraction Solvent extraction is ultimately a process of partitioning between two immiscible solvents, and for its optimization, it is necessary to know first of all the operational parameters of the system. From: Determination of Metals in Natural Waters

Liquid–liquid extraction
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
