摘要

本研究将磁性分散微固相萃取(MD-µSPE)与中空纤维液相微萃取(HF-LPME)相结合,在气相色谱-质谱联用(GC/MS)前对毒死蜱农药进行预浓缩和痕量测定。用磁铁矿纳米颗粒负载蕨类植物 Azolla filiculoides 生物质,制备磁性吸附剂(azolla@Fe3O4)。利用 FESEM、TEM、VSM、FTIR、EDX 和 XRD 方法研究了所制备的磁性纳米复合材料(MNCs)的结构特征。在拟议的 MD-µSPE/HF-LPME 方法中,MD-µSPE 步骤中的吸附/解吸变量通过田口分数因子设计进行了优化。毒死蜱在MD-µSPE的优化条件(样品体积=50 mL,接触时间=15 min,溶液pH=3,吸附剂质量=0.05 g,离子强度=0.01 mol L-1,洗脱剂类型=乙醇)下吸附后,将2.0 mL解吸后的乙醇溶液加入16 mL 10%(w/v)NaCl水溶液中进行下一步HF-LPME方法的测定,最后采用GC/MS进行分析。该方法的检出限为 0.05 μg L-1,定量限为 0.5 μg L-1,动态线性范围为 0.5-1000.0 μg L-1,预浓缩因子在 700-1050 之间,重复性(RSD%)为 6.9%。通过测定实际样品中的毒死蜱,证实了 MD-µSPE/HF-LPME 方法的适用性,相对回收率在 97.0-108.5% 之间。结果表明所开发的 MD-µSPE/HF-LPME 方法具有良好的准确度和精密度,可用于水样中痕量毒死蜱的预浓缩和测定。

Magnetic dispersive micro-solid-phase extraction integrated with hollow fiber liquid-phase microextraction for preconcentration of trace amounts of chlorpyrifos pesticide in aqueous samples

In the present study, the integration of magnetic dispersive micro-solid-phase extraction (MD-µSPE) with hollow fiber liquid-phase microextraction (HF-LPME) prior to gas chromatography–mass spectrometry (GC/MS) was developed to preconcentrate and determine trace amounts of chlorpyrifos pesticide. Azolla filiculoides fern biomass was loaded by magnetite nanoparticles to prepare magnetic adsorbent (azolla@Fe3O4). The structural characteristics of the produced magnetic nanocomposites (MNCs) were investigated by FESEM, TEM, VSM, FTIR, EDX, and XRD methods. In the proposed MD-µSPE/HF-LPME method, the adsorption/desorption variables in MD-µSPE step were optimized by Taguchi fractional factorial design. After chlorpyrifos adsorption in the optimized condition of MD-µSPE (Vsample = 50 mL, contact time = 15 min, solution pH = 3, adsorbent mass = 0.05 g, ionic strength = 0.01 mol L−1, and eluent type = ethanol), 2.0 mL of the desorbed ethanolic solution was added to 16 mL of 10% (w/v) NaCl aqueous solution for the next HF-LPME method and the final analysis was performed by GC/MS. The developed method showed a limit of detection of 0.05 μg L−1, a limit of quantification of 0.5 μg L−1, a dynamic linear range of 0.5–1000.0 μg L−1, preconcentration factors between 700 and 1050, and a repeatability (RSD%) of 6.9%. The suitability of the MD-µSPE/HF-LPME method was confirmed by measuring chlorpyrifos in real samples with relative recoveries in the range of 97.0–108.5%. The results showed good accuracy and precision of the developed MD-µSPE/HF-LPME method for the preconcentration and determination of trace amounts of chlorpyrifos in the aqueous samples.
