LIQUID–LIQUID EXTRACTION
In liquid–liquid extraction (LLE), phases A and B are both liquids. The two liquid phases must be immiscible. For that reason, LLE has also been referred to asimmiscible solvent extraction. In practice, one phase is usually aqueous while the other phase is an organic solvent.
An extraction can be accomplished if the analyte has favorable solubility in the organic solvent. Chemists have used organic solvents for extracting substances from water since the early nineteenth century
