NOVELTY - Preparing cellulose/oxidized graphene carbon aerogel involves dissolving sodium hydroxide and carbamide in water to obtain sodium hydroxide/urea aqueous solution as solvent, pre-cooling solvent obtained to (-)8-(-)15 degrees C, then absolute dry bleached flax pulp is added in amount of 1-5 wt.% with respect to mass of solvent, stirred and mixed uniformly to obtain cellulose solution. The graphene oxide is added into cellulose solution, stirred and dispersed uniformly, then heated to 40-60/oC to make gelatinized to obtain cellulose/oxidized graphene hydrogel, then freezed and dried to obtain cellulose/graphene oxide gel. The obtained cellulose/graphene oxide gel is subjected under vacuum condition for high temperature carbonization, and then acid etched, water washed, filtered, finally vacuum dried to obtain cellulose/oxidized graphite alkene carbon aerogel. The conditions for high temperature carbonization are low temperature pre-carbonizing at 180-220 degrees C for 1-3 hours. USE - Method for preparing cellulose/oxidized graphene carbon aerogel for heavy metal adsorption and waste water purification or electrode materials (claimed). ADVANTAGE - The method enables to prepare cellulose/oxidized graphene carbon aerogel that has good hydrophilicity and chemical modification.
