[BMIM]FeCl4 (1-butyl-3-methylimidazolium tetrachloroferrate) was successfully separated from a homogeneous mixture of [BMIM]FeCl4 and H2O via a simple two-step method of phase-division by adding inorganic salt plus chemical extraction, or alternatively, ultracentrifugation, or ultrastrong magnetic field. NaCl showed excellent and effective phase-dividing performance combined with chemical extraction method from the homogeneous mixture of [BMIM]FeCl4 and H2O lower to 1 v%.
