Abstract: In this study, magnetic iron oxide (Fe3O4) nanoparticles with excellent magnetic behavior were synthesized by co-precipitation method followed by their surface modification to obtain Fe3O4@SiO2NH2 and polymerization to fabricate d-phenylalanine (D-Phe) imprinted magnetic core-shell polymer (PIMP) and non-imprinted magnetic core-shell polymer (NIMP), respectively. The as-prepared PIMP and NIMP were characterized by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), and energy-dispersive X-ray spectroscopy (EDX). PIMP showed maximum adsorption capacity (3.94 mg g-1) and selectivity factor (1.55) at pH 4 while the adsorption equilibrium was achieved after 1 h. The adsorption of Phe on PIMP followed Langmuir adsorption isotherm with pseudo second order kinetics. PIMP was selective towards template (D-Phe) in the presence of interfering molecules such as L-Phe, tyrosine, and tryptophan. It was concluded that the as-synthesized PIMP is an important material to be used as a recoverable selective adsorbent and sensor for Phe
