PG - 462347 LID - S0021-9673(21)00471-4 [pii] LID - 10.1016/j.chroma.2021.462347 [doi] AB - Herein, we report the fabrication of a novel, well-defined core-double-shell-structured magnetic Fe(3)O(4)@polydopamine@naphthyl microporous organic network (MON), Fe(3)O(4)@PDA@NMON, for the efficient magnetic extraction of hydroxylated polycyclic aromatic hydrocarbons (OH-PAHs) and p-nitrophenol (p-Npn) from wastewater samples. The hierarchical nanospheres were designed and constructed with the Fe(3)O(4) nanoparticle core, the inner shell of a polydopamine (PDA) layer, and the outer shell of a porous naphthyl MON (NMON) coating, allowing efficient and synergistic extraction of OH-PAHs and p-Npn via hydrophobic, hydrogen bonding, and pi-pi interactions. The Fe(3)O(4)@PDA@NMON nanospheres were well characterized and employed as an efficient sorbent for magnetic solid-phase extraction (MSPE) coupled with high performance liquid chromatography (HPLC) for analyzing of OH-PAHs and p-Npn. Under optimal conditions, the Fe(3)O(4)@PDA@NMON-based-MSPE-HPLC-UV method afforded wide linear range (0.18-500 mug L(-1)), low limits of detection (0.070 mug L(-1) for p-Npn, 0.090 mug L(-1) for 2-OH-Nap, 0.090 mug L(-1) for 9-OH-Fluo and 0.055 mug L(-1) for 9-OH-Phe, respectively), large enrichment factors (92.6-98.4), good precisions (intra-day and inter-day relative standard deviations (RSDs); <6.4%, n=6) and less consumption of the adsorbent. Furthermore, trace OH-PAHs and p-Npn with concentrations of 0.29-0.80 mug L(-1) were successfully detected in various wastewater samples. Fe(3)O(4)@PDA@NMON also functioned as a good adsorbent to enrich a wide scope of trace contaminants containing hydrogen bonding sites and aromatic structures, highlighting the potential of functional MONs in sample pretreatment.
