UNASSIGNED: A novel surface imprinting polymer based on magnetic @entity505 nanotubes was prepared using dendritic @entity10849 as functional monomer to amplify the number of imprinted cavities. The characteristics of resulting polymers were evaluated by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and vibrating sample magnetometer (VSM). Results suggest that magnetic nanoparticles are deposited onto the surface of multiwalled @entity505 nanotubes and the imprinted shell is coated on the surface of magnetic @entity505 nanotubes with a thickness of approximately 8  nm. Magnetic imprinted polymers are sensitive to magnetic fields and can be easily separated within 3  s using an external magnet. The adsorption results indicate that the obtained imprinted polymers have fast kinetics, an ultrahigh adsorption capacity of 479.9  mg  g(-1), and satisfactory selectivity towards the template molecule. The prepared materials have excellent stability with no obvious deterioration after six adsorption-regeneration cycles. In addition, a method for determination of  @entity11676 (GA) in pomegranate rind was developed, using a combination of the prepared polymers used as solid-phase extraction (SPE) sorbents and high-performance liquid chromatography (HPLC) for rapid isolation and determination of GA. The limit of detection of the proposed method is 0.001   g  mL(-1), and the intra and inter-day @entity5494 ( @entity5494 ) are lower than 3.8  % and 5.3  %, respectively. The recoveries of GA from pomegranate rind extract are in the range 98.2-103.6  % with @entity5494 lower than 4.3  %. Graphical Abstract Selective and rapid extraction of @entity11676 in pomegranate rind.
