▎ 摘  要

NOVELTY - An environmental graphene composite adsorbent material comprises ruthenium-doped graphene and modified manganese-doped boron nitride nanotubes at mass ratio of 1:0.2-0.6. The amount of doped ruthenium atoms is ruthenium-doped graphene is 0.02-0.15%. The modified manganese-doped boron nitride nanotubes are grated with polyethyleneimine or polyethylene polyamine at grafting rate of 3-5%. USE - Environmental graphene composite adsorbent material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of adsorbent material comprising taking organic boron source, nitrogen source, manganese dichloride and iron reducing agent, mixing under inert gas environment, heating to 260-380 degrees C for 24-72 hours to obtain boron nitride nanotube precursors, heat-preserving at 200-300 degrees C under inert gas atmosphere, equipping with manganese dichloride cartridge, sintering to 500-700 degrees C for 30-60 minutes, washing with ethanol, soaking in hydrochloric acid, cleaning, partially oxidizing with ethylene polyamine in polyethyleneimine, and coupling; taking graphene oxide and ruthenium trichloride, heating to 80-1200 degrees C for 6-12 hours under inert gas atmosphere and reducing; and dissolving processed raw materials in ethanol, sonicating, and drying at 50-100 degrees C.
