    Jan 01, 2020· 4.1. Introduction. Solvent extraction (or liquid-liquid extraction) of metal ions is a technique of separating metals present, usually in the form of ions, in an aqueous solution (feed) from which they are transferred to a water-immiscible organic solvent contacted with this aqueous phase , , .It is also a method of physicochemical investigations, widely used in coordination chemistry.
