本研究提出了镍亲和固相萃取（SPE）在一些水果和蔬菜中多菌灵和噻菌灵残留量定量监测中的应用。将氧化镍纳米颗粒沉积在二氧化硅上，得到亲和吸附剂（SiO2@NiO），用于从复杂基质中选择性萃取含有咪唑基团的化合物。结合荧光检测器高效液相色谱法，优化了SiO2@NiO吸附剂对多菌灵和噻菌灵的萃取条件，建立了在10~1000 ng g−1范围内线性良好（R2> 0.998）的灵敏定量方法。两种分析物的检测限在 2.9–7.5 ng g−1 范围内，低于为这些化合物确定的最大残留限量。日内和日间精密度的相对标准偏差（RSD）均小于8.8%，具有良好的重复性。该方法已成功应用于苹果、梨、黄瓜、马铃薯、卷心菜和茄子中多菌灵和噻菌灵的分析。水果和蔬菜中加标的多菌灵和噻菌灵的回收率良好，范围为 80.0% 至 115.4%，表明该方法在监测水果和蔬菜中这两种苯并咪唑方面是可靠的。
This study presents an application of nickel affinity solid-phase extraction (SPE) for the quantitative monitoring of carbendazim and thiabendazole residues in some fruits and vegetables. The nickel oxide nanoparticle was deposited on the silica to obtain an affinity adsorbent (SiO2@NiO) for the selective extraction of the compounds containing imidazole groups from complex matrix. Coupling with high-performance liquid chromatography with a fluorescence detector, the extraction conditions of the SiO2@NiO adsorbent for the carbendazim and thiabendazole were optimized, and a sensitive quantitative method with good linearities (R2> 0.998) in the range of 10–1000 ng g−1was developed. The detection limits for the two analytes were in the range of 2.9–7.5 ng g−1, which are lower than the maximum residue limits established for these compounds. Relative standard deviations (RSDs) of intra-day and inter-day precisions were less than 8.8%, which showed perfect repeatability. The proposed method has been successfully applied to analyze carbendazim and thiabendazole in apples, pears, cucumbers, potatoes, cabbages, and eggplants. Good recoveries of carbendazim and thiabendazole spiked in fruits and vegetables were found to range from 80.0 to 115.4%, demonstrating that the proposed method was reliable in monitoring these two benzimidazoles in fruits and vegetables.
