NOVELTY - Preparation of graphene environmental pollution purifying agent comprises adding graphene to water and dispersing agent mixture, ultrasonically dispersing to obtain graphene suspension; mixing nano-mineral crystal material, carbonate and oxalic acid aqueous solution, stirring to 60-100 degrees C to obtain mixed solution; and mixing graphene suspension and mixed solution, high-speed stirring to obtain slurry solution, ultrasonically wave dispersing, standing, dehydrating, drying to obtain block-shaped product, crushing into powder, and molding. USE - Method for preparation of graphene environmental pollution purifying agent (claimed) used for air pollution and water pollution. ADVANTAGE - The purifying agent can be reused multiple times when the adsorption reaches saturation, and has stronger adsorption ability, greater adsorption capacity, faster adsorption rate, maintained normal adsorption capacity under freezing conditions, air humidity of more than 90% and hot flashes environment, and low regeneration temperature of up to 60-90 degrees C.
