Abstract: Herein, carbon fiber felt (CFF) having interwoven carbon fibers with unique properties, including high porosity, simple functionalization process, excellent adsorptive capacity, and easy operation was introduced as an efficient solid-phase microextraction sorbent . CFF was initially treated in an acidic environment resulting in AT−CFF as an adsorptive platform for the preconcentration of polycyclic aromatic hydrocarbons (PAHs). Due to the cruciality of PAHs in human health and environmental protection, AT−CFF was used to extract them from water, rice, and soil samples and analyzed by High-Performance Liquid Chromatography-Ultraviolet detection (HPLC−UV(. The various extraction parameters were optimized. The morphology, structure, and elemental composition of the prepared sorbent were characterized by field-emission scanning electron microscopy (FE−SEM), Fourier transform infrared spectroscopy (FT−IR), energy-dispersive X − ray spectroscopy (EDX), and Brunauer-Emmett−Teller (BET) analysis. The target analytes linear response (LR) was in the range of 0.005–500 ng mL –1 , with limits of detection (LOD) ranging from 0.001 to 0.015 ng mL –1 . Furthermore, the sorbent reproducibility preparation as well as its intra-day and inter-day repeatability operation (n = 5) were estimated by relative standard deviations (RSDs) values and one-way ANOVA results in detail. The method's validity was examined with the results of the recovery tests in two−level specking values.
