▎ 摘　　要

NOVELTY - A lanthanum-zirconium bimetallic graphene cellulose aerogel comprises graphene cellulose aerogel as carrier, and lanthanum and zirconium hydroxide precipitate. USE - The lanthanum-zirconium bimetallic graphene cellulose aerogel is used for removing fluorine and phosphorus from water. ADVANTAGE - The aerogel specifically adsorbs fluorine and phosphorus through specific chemical bonds, can be interfered with by other ions when a variety of interfering ions coexist, can be regenerated while still maintaining its original adsorption capacity, and has increased specific surface area, toughness and strength making it difficult to knot during use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the aerogel comprising dispersing graphene oxide in water to obtain graphene oxide dispersion, dispersing microcrystalline cellulose in water to obtain microcrystalline cellulose dispersion, dropping graphene oxide dispersion, adjusting pH of mixed solution, sonicating, adding ammonia water, sealing, heating to 90-100 degrees C for 10-16 hours, soaking solid, washing, and freeze-drying to obtain graphene cellulose aerogel; and dissolving lanthanum salt and zirconium salt in aqueous solution containing hydrochloric acid and ethanol, adding aerogel, heating, stirring, suction filtering, adding to sodium hydroxide solution, stirring, washing, and drying.
