▎ 摘  要

NOVELTY - Preparation of carbon aerogels comprises preparing graphene oxide with graphite powder by modified Hummer's method, concentrating fused graphene into 2-10 mg/mL graphene oxide aqueous solution, adjusting pH into 2-13, heating mixture under microwave oven with 400-800 W power and freeze-drying by dialysis to obtain macroscopic monolithic carbon aerogels. USE - Method for preparing carbon aerogels used in treating chromium-6 in wastewater (claimed). ADVANTAGE - The method is simple, and can be recycled through elastic deformation.
