NOVELTY - Preparation of nano-alumina-graphene oxide composite flocculating material involves ultrasonically dispersing graphene oxide and nano-alumina by improved Hummers method in deionized water for 40 minutes, respectively and mixing, adding surfactant and mixing, and heating and stirring in constant temperature water bath at 70℃. USE - Preparation of nano-alumina-graphene oxide composite flocculating material used for research and application of electrocoagulation method for simultaneous and efficient removal of microplastics and heavy metal pollutants in water environment (claimed). ADVANTAGE - The prepared flocculating material has characteristics of large specific surface area and strong adsorption capacity and its mechanism of action with heavy metal pollutants in water environment, for greatly improving simultaneous and efficient removal of microplastics and heavy metals in water environment.
