ABSTRACT
A porphyrinic metal-organic framework (PCN-224) was fabricated and used as an adsorbent for solid-phase extraction of ultratrace levels of polar sulfonamide antibiotics from food and drinking waters. The PCN-224 was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and powder X-ray diffraction analyses. Parameters affecting the extraction efficiency were optimized. The sulfonamides were quantified by liquid chromatography-tandem mass spectrometry. Figures of merit include (a) low limits of detection (0.07-0.47 ng·L-1), (b) wide linear ranges (0.5-2000 ng·L-1), and (c) good repeatabilities (2.8%-6.7%) and reproducibilities (1.7%-5.1%). The method was successfully applied to the determination of sulfonamides in food and drinking water samples. Graphical abstract A Zr(IV)-based porphyrinic metal-organic framework (PCN-224) was synthesized from a Zr6 cluster and the H2TCPP ligand. It was used for solid-phase extraction of sulfonamides from food and drinking water samples coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS) for determination.
