NOVELTY - Enriching phenolic environmental estrogen comprises e.g. using the magnetic graphene polyaniline nano composite material as an adsorption material, and adding the adsorption material to solution containing phenolic environmental estrogen and uniformly mixing to ensure sufficient adsorption, separating the adsorbent material and the solution by magnet after the adsorption is sufficient, after separating, eluting the adsorption material adsorbing the phenolic environmental estrogen by using an elution solvent, and collecting the eluted solution after the elution to obtain the enriched phenolic environmental estrogen, selecting the elution solvent from methanol, ethanol and/or acetic acid, preparing the magnetic graphene polyaniline nano composite material by using an alcohol having 1-5 carbon atoms as solvent and graphene/polyaniline, dissolving the composite material, ferric chloride and sodium acetate in the solvent and sonicating, and carrying out the reaction in an autoclave. USE - The method is useful for enriching phenolic environmental estrogen. ADVANTAGE - The method is simple and high adsorption efficiency.
