▎ 摘　　要

NOVELTY - Preparing graphene aerogel by using artemisia japonica as biomass, comprises adding 10 ml of the concentration is 3 mg/ml of the oxidation solution graphene the volume is 50 ml reaction vessel of the lining, taking 1 cm long magnetic stirring bar, taking 30 mg of artemisia japonica powder, preparing artemisia japonica powder by taking the stem of the artemisia japonica, washing the dust on the surface, drying in 60℃ oven, crushing, sieving with 60 meshes sieve, stirring for 25 minutes, taking 15 mg ascorbic acid, adding the solution and continuously stirring for 5 minutes, stirring the solution uniformly, taking out the magnetic stirrer, placing the reaction vessel sealing, placing into blast drying box, heating at 95℃ for 8 hours, cooling to room temperature, taking out the lining, transferring the hydrogel to the deionized water for removing impurity, freezing and drying the hydrogel to obtain aerogel.. USE - The method is useful for preparing graphene aerogel is useful for removing antibiotics including sulfadiazine and/or chloramphenicol in water (all claimed). ADVANTAGE - The graphene aerogel has environmental protection, and is beneficial to the protection of water bodies.
