In this study, binodal curves and tie line data of [Amim]Cl + salt (K(3)PO(4), K(2)HPO(4), K(2)CO(3)) + water aqueous biphasic systems (ABS) were measured and correlated satisfactorily with the Merchuk equation and Othmer-Tobias and Bancroft equations, respectively. [Amim]Cl could be recovered from aqueous solutions using the ABS, and the recovery efficiency could reach 96.80%. The recovery efficiency was influenced by the concentrations of the salts and their Homeister series: K(3)PO(4) > K(2)HPO(4) > K(2)CO(3). Our method provides a new and effective route for the recovery of hydrophilic IL using [Amim]Cl + salt + water ABS from aqueous solutions.
