extraction as a separation technique

Liquidliquid extraction

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).
