▎ 摘  要

NOVELTY - Preparation of adsorption resin involves: 1) dissolving preset amount of acrylamide in sodium hydroxide solution, then adding graphene oxide and stirring to form mixed solution; 2) heating the mixed solution in water bath, continuously stirring and reacting to form modified oxidized graphene; 3) drying the modified oxidized graphene to constant weight, then grinding to form powdered modified graphene oxide; 4) dissolving preset amount of divinylbenzene in tetrahydrofuran solution to form a mixed solution; 5) dripping the mixed solution into powdered modified graphene oxide, to form a mixture; 6) heating the mixture, cooling to room temperature and drying until tetrahydrofuran is completely volatilized, then drying the mixture. USE - Method is used for preparing adsorption resin used in waste gas treatment. ADVANTAGE - The method enables to prepare graphene oxide@polydivinylbenzene resin having improved adsorption performance, when used in water treatment procedures. When the adsorption resin, absorbs volatile organic compounds (VOCs) waste gas, graphene oxide absorbs water molecules prior to polydivinylbenzene, and prevents the polydivinylbenzene pore structure from collapsing, to ensure the adsorption performance of polydivinylbenzene on VOCs.
