Abstract:

By a simple and low-cost method, zeolitic imidazole framework-67 was synthesized. It was used as a solid-phase microextraction coating. The solid-phase microextraction was used for the extraction of 1-octanol, 1-nonanol, 1-decanol and 1-undecanol from the headspace of an aqueous solution. Separation and determination of the analytes were performed by a gas chromatography followed with a flame ionization detector. Several techniques such as field emission scanning electron microscopy, X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy analysis, energy-dispersive X-ray spectroscopy, thermal gravimetric analysis and nitrogen adsorption–desorption experiments have been utilized for characterization of the coating material. The effective parameters on the extraction of the alcohols were investigated and optimized. Under the optimum conditions, four kinds of alcohol including 1-octanol, 1-nonanol, 1-decanol, and 1-undecanol were extracted and determined with linear ranges (0.5–100.0 μg L−1 with R2 ≥ 0.9945), limits of quantification of 0.5 µg L−1 and limits of detection that were calculated based on 3(Sd)blank/m (0.17 µg L−1) for all of the analytes. The average repeatability and fiber-to-fiber reproducibility were 7.7% and 11.7%, respectively. Additionally, 1-octanol, 1-nonanol, 1-decanol, and 1-undecanol in alcoholic beverages were determined with a mean recovery of 90.9–92.5% and relative standard deviations less than 9.8%.
