Liquid Liquid Extraction

Liquid-Liquid extraction is a method by which a compound is pulled from a solvent to another solvent where both the solvents are not miscible. The most common method of liquid-liquid extraction is performed using a separatory funnel. Other important liquid-liquid extraction processes are multistage countercurrent continuous processes, mixer-settlers, centrifugal extractors, extraction without chemical change.

The efficiency of a liquid liquid extraction can be enhanced by adding one or more extractants to the solvent phase. The extractant interacts with component increasing the capacity of the solvent for to recover the solute from the extract phase the extractant-solute complex has to be degraded. The major applications exist in the biochemical or pharmaceutical areas, for the separation of antibiotics and protein recovery. In the inorganic chemical field liquid-liquid extraction used to recover high-boiling components such as phosphoric acid, boric acid, and sodium hydroxide from aqueous solutions.
