Facile preparation of a chicken feet yellow membrane coated fiber for application in solid‐phase microextraction

Abstract

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.

Introduction of a bio-waste/reduced graphene oxide nanocomposite as a new bio-sorbent for the solid-phase extraction of some polycyclic aromatic hydrocarbons

“…At first, 0.75 g CFYM powder was added to 10 mL thioglycolic acid solution. Then, the reaction mixture had been heated at 90 o C until the yellow powder was completely dissolved and a homogeneous gel appeared [12]. Then, the heater was switched off, 0.25 g rGO was dispersed into the mixture, and a sufficient concentrated gel was obtained.…”

Determination of pesticides residues in vegetable and fruit samples by solid‐phase microextraction with a covalent organic framework as the fiber coating coupled with gas chromatography and electron capture detection

“…SPME, which was first reported by Pawliszyn and his colleagues , integrates sampling, extraction, and sample introduction into one step, and is environmentally friendly and solvent‐free. In combination with HPLC or GC, SPME has been widely utilized for the determination of various organic compounds in biological, environmental and food samples . Since SPME is based on the distribution equilibrium of the analytes between the sample matrix and the adsorbent coated on the fiber , the fiber coating materials play a key role for the SPME performance.…”

Improvement of dispersive liquid‐liquid microextraction robustness by performing consecutive extractions: Determination of polycyclic aromatic hydrocarbons in Brazilian sugar cane spirits by GC‐MS

“…Nevertheless, as an advantage, they are designed to promote the exhaustive extraction of the analytes from the sample, improving the robustness in terms of sample‐to‐sample recoveries. On the other hand, in miniaturized sample preparation procedures, such as solid phase microextraction (SPME) , liquid phase microextraction (LPME) and dispersive liquid‐liquid microextraction (DLLME) , the extraction phase volume required is minimal, making the procedure simpler and more economical. Typically, these procedures promote an equilibrium rather than exhaustive extraction.…”
