摘要
In this work, triazine-based porous organic polymer (TAPT-BPDA) synthesized by simple solvothermal method with stable chemical properties was employed as pipette tip solid-phase extraction (PT-SPE) adsorbent for the extraction of sulfonamides for the first time. Under the optimal conditions, good linearities (1–300 μg L−1, R2 ≥ 0.9987) and low limits of detection (0.10–0.28 μg L−1) were obtained. The recoveries of sulfonamides in meat, egg and milk samples were in the range of 76.1–114.0 %. The prepared TAPT-BPDA showed good reusability with the recoveries of sulfonamides remained above 80.0 % after eight recycles. The adsorption mechanism between SAs and adsorbent might be the combined effects of electrostatic interactions, hydrogen bonding and π-π interactions. The results demonstrated potential applications of a TAPT-BPDA-based PT-SPE-HPLC method for the analysis of trace sulfonamide residues in food samples.
