Abstract Information :

By a simple and low-cost method, zeolitic imidazole framework-67 was synthesized as a solid-phase microextraction coating. It was used for the extraction of alcohols from the headspace of an aqueous solution. Separation and determination of the analytes were performed using gas chromatography with a flame ionization detector (GC-FID). Several techniques have been utilized for the characterization of the coating material. Under the optimum conditions, four alcohols 1-octanol, 1-nonanol, 1-decanol, and 1-undecanol were extracted 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, the alcohols in alcoholic beverages were determined with a mean recovery of 90.9–92.5 % and RSDs less than 9.8%.
