▎ 摘 要
NOVELTY - Preparing graphene oxide aerogel capable of efficiently treating petroleum desorption liquid comprises (1) adding graphene powder to potassium permanganate solution and stirring to obtain graphene oxide, (2) adding the graphene oxide in to the deionized water, and ultrasonically dispersing or mechanical stirring for 30-60 minutes until uniform mixing to obtain graphene oxide solution, (3) mixing the graphene oxide solution with the polypyrrole and the activated carbon powder, mechanically stirring for 40-50 minutes, adding to the hydrothermal kettle, and processing at a temperature of 90-200 degrees C for 1-24 hours to obtain a graphene oxide aerogel, (4) soaking the obtained graphene oxide aerogel in an aqueous solution for 1-22 hours, then pre-freezing at -20 to -4 degrees C, and then freeze-drying to obtain graphene aerogel with high adsorption performance, and (5) applying the graphene aerogel with high adsorption performance to the petroleum desorption liquid treatment. USE - The method is useful for preparing graphene oxide aerogel capable of efficiently treating petroleum desorption liquid. ADVANTAGE - The method: is simple and environmentally friendly, and contributes the development of graphene aerogel research in the field of environmental protection.
