The trace levels and severe matrix interferences greatly limited the determination of stable, persistent, long-range-transported perfluoroalkanesulfonic acids (PFSAs) in complex environments. Here, we design prepare first fluorinated nonpolar 3D COF (TFPM-Pa-CF3) as an adsorbent, consisting tetrakis(4-formylphenyl)methane (TFPM) 2,5-diaminobenzo-trifluoride (Pa-CF3) for adsorption extraction PFSAs. proposed TFPM-Pa-CF3 demonstrates excellent capacity (509.1 mg g–1) rapid kinetics (5 min) PFSAs attributed to synergistic effects F–F, hydrophobic, electrostatic interactions. Furthermore, is grown situ on a stainless needle coupled with ambient probe nanoelectrospray ionization mass spectrometry (PESI-MS) develop direct method low limit detection (0.05–0.86 ng L–1) wide linear range (1–10,000 perfluorooctanesulfonate its alternatives environmental soil, algae water. This work unlocks efficient or removal environment, facilitating solution critical problems.
