Abstract

•We have for the first time synthesized phenylalanine-modified magnetic Fe3O4 nanoparticles to adsorb ciprofloxacin.•The Fe3O4@Phe NPs exhibit high dispersion and excellent magnetic properties.•Phenylalanine can significantly improve the adsorption capacities of CIP on Fe3O4@Phe NPs.•The adsorption mechanisms for CIP consist of electrostatic interactions, hydrogen bonding, hydrophobicity and π-π interactions.
