Extraction, Liquid–Liquid

Abstract Liquid‐liquid extraction, also known as solvent extracting, is a well‐established separation technique that depend on the unequal distribution of a solute between two immiscible liquids. The initial feed liquid containing the solute is brought into contact with a solvent which is selected to have a greater affinity for the solute. The partition of the solute can be enhanced by adding a chemical extractant to the solvent; this practice …
