Liquid–liquid extraction
METHOD TO SEPARATE COMPOUNDS BASED ON THEIR RELATIVE SOLUBILITIES IN TWO DIFFERENT IMMISCIBLE LIQUIDS, USUALLY WATER AND AN ORGANIC SOLVENT; EXTRACTION OF A SUBSTANCE FROM ONE LIQUID INTO ANOTHER LIQUID PHASE
Solvent extraction; Solvent Extraction; Two-phase liquid extraction; Two Phase Liquid Extraction; Two phase liquid extraction; Liquid liquid extraction; Liquid-liquid extraction; Countercurrent solvent 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 into another liquid phase, generally from aqueous to organic.
