  • C18 functionalization was achieved via C-O-Si bonding.
  • Gas chromatography (GC) was used to analyze extracted PAHs.

    • Main Results:

    • The C18-GO fiber demonstrated excellent extraction efficiency and selectivity for PAHs.
    • The fiber exhibited high rigidity, long service life, and stability in organic solvents, acidic/alkaline solutions, and at high temperatures.
    • Low detection limits (<0.08 μg L⁻¹) and wide linear calibration ranges were achieved for PAHs.
    • Relative standard deviations for repeatability and reproducibility were <7.26% and <17.25%, respectively.
    • The method was successfully applied to determine PAHs in real water samples.

    Conclusions:

    • A novel and robust C18-GO SPME fiber was successfully prepared.
    • The developed SPME-GC method provides a sensitive and reliable approach for PAH determination.
    • The fiber's stability and reusability make it a promising tool for environmental analysis.
