The present invention relates to a method for purifying boron nitride nanotubes with a simplified process. Specifically, the purification method includes preparing a starting solution containing a boron nitride nanotube (BNNT), a dispersant, and a solvent, collecting the supernatant by centrifuging or leaving the starting solution, and acid in the supernatant. Including the step of introducing (Acid) and filtering the resultant. |
