Metal Extraction with Ionic Liquids- based Aqueous Two - Phase System

The use of an Ionic Liquid for metal separation in various areas of human life. Although ionic liquids (ILs) have excellent properties, their use as extracts in solvent extraction hasn't eliminated the problems associated with the use of organic solvents. The efficiency and selectivity of metal extraction from industrial wastewater using ionic liquids composed of various cations and anions are prioritized. Aqueous two-phase system (ATPS) is a liquid-liquid fractionation technique that has garnered attention in industry and academia due to its high possibilities for the extraction, separation, purification, and betterment of proteins, membranes, viruses, enzymes, nucleic acids, and other biomolecules. However, the method's partition behavior is complex and difficult to predict. According to an ongoing study, it has also been employed successfully in the detection of veterinary drug residues in food, the separation of precious metals, sewage treatment, and a wide range of other applications. The ATPS has a high recovery yield and is simple to scale up. It is also a very cost-effective and ecologically friendly method. The purpose of this article is to provide an overview of ATPS basics, enhancement, and applications.
