description The invention discloses a method for removing 1-butyl-3-methylimidazol ionic liquid pollutants out water by using a nitric acid oxidized ordered mesoporous carbon material CMK-3. The method comprises the following steps: firstly, adding an ordered mesoporous carbon material CMK-3 into a nitric acid aqueous solution, and performing heating reaction to obtain the nitric acid oxidized ordered mesoporous carbon material CMK-3; adding the prepared CMK-3 into a polluted aqueous solution containing 1-butyl-3-methylimidazol ionic liquid, performing oscillation adsorption, and filtering to remove the nitric acid oxidized ordered mesoporous carbon material CMK-3 with adsorbed ionic liquid; and finally, regenerating an adsorbent by using hydrochloric acid. By virtue of simple nitric acid oxidation treatment, rich surface functional groups mainly including carboxyl groups are loaded on the surface of the ordered mesoporous carbon material, so that a high specific area of the mesoporous carbon material is ensured, a large
