This work introduces a novel fiber based on chicken feet yellow membrane as a new coating material for application in solid‐phase microextraction methods for the first time. The chicken feet yellow membrane suspension was easily prepared and coated on the surface of an end‐closed glass tube through the dip‐coating procedure. The coating material was characterized by using scanning electron microscopy, Fourier transform infrared spectroscopy and X‐ray diffraction techniques. The performance of the prepared fiber was evaluated thorough the solid‐phase microextraction of polycyclic aromatic hydrocarbons followed by high‐performance liquid chromatography with UV detection. Under the optimized experimental conditions, linearity of responses were obtained in the range 0.005–100.0 μg L−1 with the determination coefficients 0.996–0.998. The limits of detection varied between 1.44 and 18.32 ng L−1 and relative standard deviation values was obtained in the range 4.4–8.2%. The intended method was employed for the study of the real samples with reasonable recoveries values ranged between 80 and 110%. The analytical performance of new fiber suggests promising prospects in sample preparation due to easy fabrication, low cost, environmentally friendly, chemical and mechanical stability, high extraction efficiency, long life span, and easy operation.

A green biocomposite of sunflower stalks and graphitic carbon nitride nanosheets has been applied as a solid-phase extraction adsorbent for sample preparation of five polycyclic aromatic hydrocarbons in different solutions using high-performance liquid chromatography with ultraviolet detection. Before the modification, sunflower stalks exhibited relatively low adsorption to the polycyclic aromatic hydrocarbons extraction. The modified sunflower stalks showed increased adsorption to the analytes extraction due to the increase in surface and existence of a π-π interaction between the analytes and graphitic carbon nitride nanosheets on the surface. Under the optimal conditions, the limits of detection and quantification for five polycyclic aromatic hydrocarbons compounds could reach 0.4-32 and 1.2-95 ng/L, respectively. The method accuracy was evaluated using recovery measurements in spiked real samples and good recoveries from 71 to 115% with relative standard deviations of <10% have been achieved. The developed method was successfully applied for polycyclic aromatic hydrocarbons determination in various samples-well water, tap water, soil, vegetable, and barbequed meat (kebab)-with analytes contents ranging from 0.065 to 13.3 μg/L. The prepared green composite as a new sorbent has some advantages including ease of preparation, low cost, and good reusability.
