▎ 摘  要

NOVELTY - Preparing molecular bottle brush reverse phase adsorbent (I) involves using iron oxide nanoparticle which is polydopamine. The adsorbent is dopamine-coated magnetic graphene matrix, loading magnetic graphene on the surface of graphene to obtain iron oxide nano-particles, and coating surface of the magnetic graphene with polydopamine to obtain final product. USE - Method for preparing molecular bottle brush reverse phase adsorbent used for separation and enrichment of bisphenol A in water sample (claimed). ADVANTAGE - The method enables to prepare molecular bottle brush reverse phase adsorbent which has high adsorption capacity, long service life, and has improves separation and concentration efficiency of bisphenol A. DETAILED DESCRIPTION - Preparing molecular bottle brush reverse phase adsorbent of formula (I) involves using iron oxide nanoparticle which is polydopamine. The adsorbent is dopamine-coated magnetic graphene matrix, loading magnetic graphene on the surface of graphene to obtain iron oxide nano-particles, and coating surface of the magnetic graphene with polydopamine to obtain final product. m=50-200; and n=10-30.
