▎ 摘　　要

NOVELTY - Magnetic material comprises graphene, polyaniline, polyaminobenzyl alcohol composite material, prepared by dissolving ferric chloride, and sodium acetate in alcohol containing 1-5 carbon atom, subjecting for ultrasonic treatment, reacting in the high pressure reaction kettle to obtain magnetic material. The graphene, polyaniline, polyaminobenzyl alcohol composite material is prepared by e.g. after ultrasonic treatment of graphite oxide, mixing it with solvent, obtaining graphene solution, adding aniline and hydrochloric acid solution and stirring. USE - The magnetic material is used for absorbing bisphenol A (claimed). ADVANTAGE - The magnetic material can achieve chemical stable property, has large surface area, and strong absorbing performance. DETAILED DESCRIPTION - Magnetic material comprises graphene, polyaniline, polyaminobenzyl alcohol composite material at ratio of 1-10:1-10:1-10, prepared by dissolving ferric chloride, and sodium acetate in alcohol containing 1-5 carbon atom, subjecting for ultrasonic treatment, reacting in the high pressure reaction kettle to obtain magnetic material. The graphene, polyaniline, polyaminobenzyl alcohol composite material is prepared by after ultrasonic treatment of graphite oxide, mixing it with solvent, obtaining graphene solution, adding aniline and hydrochloric acid solution of o-amino benzyl alcohol and stirring uniformly in the graphene solution, obtaining mixed liquid, adding hydrochloric acid solution containing ammonium persulfate in the mixed liquid, and reacting to obtain composite material. An INDEPENDENT CLAIM is also included for enrichment of bisphenol A comprising using absorbing magnetic material as adsorption material, adding the adsorption material to solution containing bisphenol A and mixing uniformly, carrying out full adsorption, absorbing full use magnet for absorbing material and solution separating, after separation using elution solvent for adsorption using adsorption material for bisphenol A elution, collecting the solution after elution.
