摘要: The quality and safety of agricultural products are important factors in safeguarding human health and promoting sustainable agricultural development. However, for the purpose of improving the yield and quality, the misuse of pesticides often occurs, causing pesticide residues to remain in vegetables, posing threats to both the environment and human health. In order to detect and adsorb pesticide residues in vegetables, a coral-like novel magnetic porous nanomaterial (Fe@MDZ) was developed in this study as an adsorbent to adsorb thiabendazole (TBZ). Fe@MDZ has a large specific surface area (229.254 m2/g) and high saturation magnetization intensity (57.38 emu/g) with good adsorption capacity for TBZ. When the initial concentration was 2 mg/L, the adsorption capacity for TBZ was 1.23 mg/g. The static adsorption process matched the Langmuir isotherm model and was consistent with the pseudo-second-order kinetic model. In addition, the recovery of TBZ in both tomato and Chinese cabbage samples at different concentrations was above 70%. This work provides a new idea for the detection of TBZ pesticide residues in vegetables.
