Separation of cobalt and nickel using a thermomorphic ionic-liquid-based aqueous biphasic system

Author affiliations

Abstract

A [P44414][Cl]–NaCl–H2O ionic liquid-based aqueous biphasic system shows promising results for the separation of cobalt(II) and nickel(II) by homogeneous liquid–liquid extraction. The extracting phase consists of a hydrophilic ionic liquid that is salted-out by sodium chloride, indicating that there is no need for using hydrophobic ionic liquids.
