NOVELTY - Preparing modified acidic cation exchange resin comprises (1) preparing a pure aqueous solution, pre-polymerizing the acrylate copolymer into a macromolecular plasticizer in the aqueous solution, and then add graphite, glycine and bioflavonoids for stirring and mixing, (2) polymerizing styrene and divinylbenzene into white porous spheres under the condition of adding inorganic whiskers and graphene powder into the mixed solution, (3) adding the white porous spheres in a Soxhlet extractor, and sealing Soxhlet extractor with a round-bottomed flask filled with toluene, heating, extracting the white porous spheres and adding the white porous spheres, transferring to another flask, adding pure water, heating and stirring, and drying in an oven and (4) sulfonating the dried white porous spheres into acidic cation exchange resins, and complexing the acidic cation exchange resins with amphoteric metal oxides to form acidic cation exchange resin spheres with stable structures. USE - The method is useful for preparing modified acidic cation exchange resin. ADVANTAGE - The method can reduce the toxic substance in the acidic cation exchange resin manufacturing process, the acidic cation exchange resin is safer.
