[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation for separating mixtures by taking advantage of the different solubilities of components in solvents, that is, a method for transferring solute substances from one solvent to another by taking advantage of the different solubilities or distribution coefficients of substances in two mutually insoluble solvents, which is widely used in chemical, metallurgical, food and other industries, and is commonly used in petroleum refining industry.
