Two Phase liquid extraction, also known as aqueous two phase extraction, is a unique form of Solvent extraction. In standard liquid extraction, an aqueous liquid is brought into contact with an organic solvent, and compounds in the aqueous solution are separated based their relative solubility in the two phases. In an aqueous two phase extraction, compounds are still separated based on their solubility, but the two immiscible phases are both water-based, an aqueous two phase system.
