Herein, for the first time, a new method for the simultaneous extraction of phenol (Ph), nitrophenols (NPs), and chlorophenols (CPs) as the priority pollutants was proposed using a magnetic porous carbon coated with poly(2,6-diaminopyridine). The analytes were separated/determined by an HPLC device coupled to a diode array detector. Magnetic porous carbon was obtained by the pyrolysis of MIL-53(Fe) as a precursor and then functionalized with a layer of poly(2,6-diaminopyridine). Next, the synthesized adsorbent was identified by various methods, including FT-IR, XRD, SEM, VSM, surface analysis, and TEM techniques. After that, the design of the experiment strategy was used to identify and optimize the extraction variables. The LODs and linear range were obtained in the range of 0.04–0.15 µg/L and 0.1–500 µg/L, respectively. The one-day RSDs and day-to-day RSDs were gained in the range of 4.2–9.5 % and 5.0–12.5 %, respectively. The enrichment factors and extraction recoveries were obtained in the range of 208–378 and 41.6–75.6 %, respectively. Eventually, the outlined method was employed to analyze diverse water/wastewater samples satisfactorily.
