水素結合有機骨格吸着剤を用いた麦芽中の農薬モニタリングのための強化された分析性能

In this work, a new hydrogen-bonded organic framework was synthesized from hexanedioic acid and trimesic acid with solvent evaporation method. It was used as a sorbent to separate some pesticides from different malt samples. To prove the successful synthesis of the sorbent, characterization was carried out using various techniques including Fourier transform infrared spectrometry, X-ray diffraction, scanning electron microscopy, and Brunauer-Emmett-Teller nitrogen sorption/desorption. Accepted extraction recoveries (40-95 %), high enrichment factors (192-476), low limits of detection and quantification (0.47-1.19 and 1.55-3,92 µg l^-1, respectively), and wide linear ranges (5.00-1000 µg l^-1) were the analytical features of this approach. The presence of oxadiazone and tebuconazole was verified in mapoyhoe sample. The concentrations of oxadizone and tebuconazole were obtained from gas chromatograph-flame ionization detector data and they were 10 ± 0.1 and 12 ± 0.1 µg l^-1 (n = 3), respectively. Simple, cost-effective, and environmentally friendly were the key features of the developed method.
