The present invention relates to an apparatus for reuse of an ionic liquid, capable of purifying an ionic liquid used for purification of an organic material to be reused, and a method therefore. The method includes: a mixing step of mixing a first ionic liquid and a low-purity organic material; a purification step of purifying the low-purity organic material in the first ionic liquid; and a filtering step of separating a second ionic liquid from a mixture in which the second ionic liquid, which is ionic liquid after the purification step, and the organic material purified in the purification step are included. The filtering step includes: an injection step of injecting the mixture into the inner space of a filter housing provided in a filter unit; a pressure difference generation step of generating a pressure difference between the front part of a filter member, which is installed inside the filter housing, and the rear part of the filter member; and a separation step of separating the second ionic liquid from the mixture by using the filter member. |
