Abstract: The present disclosure relates to an apparatus and a method for purifying BNNT and purified BNNT, more specifically to an apparatus and a method for purifying BNNT, which allow separation of pure BNNT from synthesized BNNT wherein various impurities are included with high purification efficiency and separation of BNNT based on length, and purified BNNT. The method for purifying BNNT according to the present disclosure is characterized in that pure BNNT is separated from synthesized BNNT based on length by inputting a mobile phase including synthesized BNNT into a column chromatography device.
