▎ 摘　　要

NOVELTY - Multi-porous graphene polymers comprises graphene and polyferric chloride in a mass ratio of 1:5-5:1, where the porosity is 20-95 %, where the polymer via crosslinking inorganic high molecular polymer ferric chloride to obtain multi-hole polymer and organic substance in water form flocculating precipitate and removal. USE - The multi-porous graphene polymers is useful for sewage (heavy metals, grease) adsorption treatment (claimed). ADVANTAGE - The method: helps in chemical oxygen demand adsorption after the removal of flocculation sedimentation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing multi-porous graphene polymers comprising (a) taking anhydrous ethanol and auxiliary agent, where the inert gas introduced a reaction kettle, microwave pyrolysis to obtain grapheme, (b) via ultrasonic mixing with sulfuric acid and nitric acid mixed solution and graphene, to obtain grapheme oxide, (c) taking polymer ferric chloride solution and sodium borohydride aqueous solution, ultrasonically dispersing, oxidation of graphene solution to obtain polymeric ferric chloride chain of porous graphene polymer.
