The performance of headspace solid-phase microextraction (HS-SPME) was upgraded by easy and low-cost preparation of a new nanocomposite fiber. A polypyrrole/chromium-based metal–organic framework, PPy@MIL-101(Cr), nanocomposite was electrochemically synthesized and simultaneously coated on a steel wire as a microextraction sorbent. The morphology and chemical structure of the prepared nanocomposite was characterized by Fourier-transform infrared spectrometry (FT-IR), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX) techniques. The microsorbent was used for sampling of methyl-tert-butyl ether (MTBE) in solid samples, through an HS-SPME sampling strategy, followed by GC-FID measurement. The optimal experimental conditions, including extraction temperature, extraction time, and GC desorption conditions, were evaluated and optimized. The proposed procedure showed good sensitivity (limit of detection was 0.01 ng·g−1) and precision (relative standard deviation was 8.4% for six replicated analyses). The calibration curve was linear over the range of 5–40,000 ng·g−1, with a correlation coefficient of 0.994. The limit of quantification was 0.4 ng·g−1. The fabricated fiber exhibited good repeatability and reproducibility for the sampling of MTBE, with average recovery values of 88–114%. The intra-fiber and inter-fiber precisions were found to be 8.4% and 19%, respectively. The results demonstrated the superiority of the PPy@MIL-101(Cr)-coated fiber in comparison with handmade (polypyrrole, PPY) and commercial fibers (polyacrylate, PA; polydimethylsiloxane, PDMS; and divinylbenzene/carboxen/polydimethylsiloxane, DVB/CAR/PDMS) for the analysis of solid samples. The developed method was successfully employed for the analysis of MTBE in different soil samples contaminated by oil products.

“…In situ fiber solid phase microextraction [1] (SPME) is a mature quantitative sampling technique that enables trace-level multianalyte detection for a wide range of sample matrices [2][3][4][5] and environmental conditions [6][7][8][9]. In fiber SPME, a syringe-like device houses a retractable fused silica fiber with an immobilized stationary extraction phase at its tip, which is inserted into the sample headspace or liquid to collect and concentrate analytes via absorption and/or adsorption, until ideally equilibrium is achieved.…”

“…As a high sensitive and field-portable analytical instrument, ion mobility spectrometry (IMS) has been proved to be a powerful technique for the on-site detection of trace amount of chemical warfare agents (CWAs) [7,8], explosives [9,10], narcotic drugs [11,12], and other hazardous chemicals [13,14]. Since 1971, the use of IMS analyzers has been investigated in the detection of nitrobenzene compounds particularly [15,16].…”
