Abstract: A novel adsorbent with high selectivity for fluoroquinolone (FQ) compounds was developed, based on the surface functionalization of magnetic carboxylated cellulose nanocrystals (M-CCNs) with molecularly imprinted polymer (MIP) comprising amine moieties. The imprinting was achieved by a radical polymerization technique, which uses glycidyl methacrylate, tetraethylenepentamine, ofloxacin, ethylene glycol dimethacrylate, and azobisisobutyronitrile as the functional monomer, active groups provider, template molecule, crosslinking agent, and initiator, respectively. The developed material (M-CCNs@MIP) was comprehensively characterized and shown to exhibit high adsorption capacity and selectivity with rapid equilibration time. Moreover, the adsorption isotherms could be well-fitted with the Freundlich model, and the adsorption kinetics followed the pseudo-second-order model. The maximum adsorption capacities for M-CCNs@MIP after 2 and 20min were 34.09 and 40.65 mg g-1, respectively, compared to 9.98 and 15.28 mg g-1 observed for the unimprinted polymer (M-CCNs@NIP). By coupling the M-CCNs@MIP adsorbent with high-performance liquid chromatography, an approach was established to enhance the selective adsorption of seven structurally similar FQ compounds in river water samples. The recoveries of the seven FQs ranged from 81.2 to 93.7%, and the limits of detection were between 5.4 and 12.0 ng mL-1. The M-CCNs@MIP adsorbent also retained good performance after seven consecutive cycles of reuse
