Abstract

A porous aromatic framework (PAF), PAF-56P, with a large surface area, high solvent stability and good thermostability, was prepared and utilized as a solid phase microextraction (SPME) adsorbent coating for the efficient enrichment of some triazole fungicides. Coupled with gas chromatography-mass spectrometric detection, a PAF-56P based SPME method achieved good analytical performance such as low limits of detection (0.15–1.70 ng g−1), wide linear range (2.50–250 ng g−1) and good repeatability (relative standard deviations, RSDs < 9.2%). The PAF-56P SPME coating had a high durability for 100 replicate extractions without a significant decrease in extraction capability. The developed method was feasible for the analysis of triazole fungicides from fruits and vegetables with satisfactory recoveries (81.3–119%).
