Fabrication of robust polyimide-coated solid phase microextraction fibers for efficient extraction of fifteen polycyclic aromatic hydrocarbons from environmental water

Year: 2025

Type: article

Abstract: ) for polycyclic aromatic hydrocarbons in water samples. The method demonstrated excellent repeatability, with single-fiber repeatability ranging from 2.9% to 6.9% and fiber-to-fiber reproducibility between 3.9% and 11.5%. The recoveries of the analytes were between 82.7% and 107.2%. Additionally, the fiber exhibited outstanding durability, maintaining its extraction performance after more than 150 uses. The developed method was successfully applied for the determination of polycyclic aromatic hydrocarbons in river, pond, and sewage water samples, highlighting its potential as a sensitive, reliable, and cost-effective tool for environmental analysis.
