▎ 摘  要

NOVELTY - The preparation of graphene solar water cleaning foam, involves (1) subjecting graphite powder to oxidation treatment to obtain graphene oxide aqueous solution, (2) mixing aqueous graphene oxide solution with low freezing point solvent to obtain mixed solution, (3) freeze-drying the mixed solution to obtain graphene oxide foam, and (4) reducing the graphene oxide foam at high temperature. USE - Preparation of graphene solar water cleaning foam for use in sewage purification treatment (claimed). ADVANTAGE - The method enables preparation of graphene solar water cleaning foam ensuring high ion removal rate greater than or equal to 99.5% and increased bacteria removal rate greater than or equal to 99.9% by simple process.
