Abstract The present study introduces a high efficiency metal alloy-based solid-phase microextraction (SPME) fiber coated with a green biowaste nanocomposite of chicken feet yellow membrane
mixed with graphene oxide (CFYM/GO). An Al/Cr commercial heating element (aluchrom, AC)
has been selected as the fiber substrate and designed as coiled form (CAC-SPME) to enhance its
extraction and pre-concentration capacity. The fabricated fiber, CAC-SPME/CFYM/GO, has been
employed for the extraction and pre-concentration of some commonly seen PAHs in different standard/real samples prior to their high performance liquid chromatography- ultraviolet (HPLC-UV)
analyzing. The synthesized materials and the fibers surface were characterized by field emission
scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier-transform infrared
spectroscopy analysis and Brunauer-Emmett-Teller surface area analysis. Under the optimized
experimental conditions, low detection limits (LOD, 0.039–0.30 mg L–1), wide linear ranges (LR,
0.13–643 mg L–1) and good relative recoveries (RR, 76.20–105.60%) were achieved for all the target
analytes. The materials applied to prepare this fiber were low-priced and accessible and also eliminated the need for expensive coating substances. In addition, using of the AC alloy substrate was
increased the fiber physicochemical resistance and solved the breakage drawback of the conventional SPME fibers. Moreover, simple fabrication, high rigidity, long service life and high extraction
capacity were some of the other advantages of the suggested fiber. Therefore, the proposed method
can be utilized successfully for the routine analysis of PAHs in different matrixes.
