▎ 摘　　要

NOVELTY - A magnetic graphene polyaniline nanocomposite material is prepared from dissolving graphene/polyaniline composite having ratio of 1-5:1-10:1-10, iron(III) chloride and sodium acetate into solvent comprising alcohol containing 1-5C, ultrasonically processing, and reacting into high pressure kettle. USE - Magnetic graphene polyaniline nanocomposite material. ADVANTAGE - The material has high adsorption efficiency and simple operation, overcomes easy to stack graphene layer preparation and easy to defect pure polyaniline, shows absorbing property, and increases adsorption efficiency for phenolic estrogen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for enrichment method of phenolic environmental estrogen comprising using magnetic graphene polyaniline nanocomposite material as absorbing material, adding into solution containing phenolic environmental estrogen, mixing, adsorbing, separating, eluting using elution solvent, and collecting. The solvent is methanol, ethanol and acetic acid.
