Abstract: A method for recovering a cation component of a neutralized-salt type ionic liquid, characterized by comprising a first step, in which an aqueous solution of the neutralized-salt type ionic liquid is mixed with a water-incompatible organic solvent to prepare a liquid separating into two phases, i.e., an aqueous phase and an organic phase, a second step, in which the liquid separating into two phases is mixed with a water-soluble strong alkali so that the amount of the strong alkali is 20% by mass or larger with respect to the water contained in the aqueous phase, thereby regenerating the cations of the neutralized-salt type ionic liquid present in the aqueous phase, into a neutral substance and moving the neutral substance from the aqueous phase to the organic phase, and a third step, in which the organic phase containing the neutral substance is recovered by a liquid-separating operation.
