Abstract

In this research, a straightforward sample treatment for multiresidue pesticide evaluation of onion samples was developed using the solid-phase extraction/quick, easy, cheap, effective, rugged, and secure (SPE/QuEChERS) method. The suggested technique is based on acetonitrile liquid-liquid partitioning, then follows dispersive solid-phase extraction with ZrO₂ particles for extract purification. ZrO₂ is synthesized via co precipitation and analyzed via XRD, FTIR, and SEM. ZrO₂ has been demonstrated to be more effective than normal graphitized carbon black at eliminating pigment. Thirty-five pesticides from various chemical classes were examined using gas chromatography and tandem mass spectrometry (GC-MS/MS) to assess the outlined technique. Most analytes had recoveries in the range of 74–105%, with relative standard deviations of less than 14%. The linearity, precision, and accuracy of GC-MS/MS were adequate. The validated technique was applied effectively to onion samples from the farmer’s field.

使用含氧化锆纳米粒子的改良 QuEChERS 方法，采用气相色谱-质谱/质谱法分析洋葱中的多残留农药

本研究采用固相萃取/快速、简便、廉价、有效、坚固和安全（SPE/QuEChERS）方法，开发了一种用于洋葱样品多残留农药评估的直接样品处理方法。所建议的技术以乙腈液-液分配为基础，然后用 ZrO2 颗粒进行分散固相萃取，以纯化提取物。ZrO2 通过共沉淀合成，并通过 XRD、FTIR 和 SEM 进行分析。实验证明，在消除色素方面，ZrO2 比普通石墨化炭黑更有效。使用气相色谱和串联质谱法（GC-MS/MS）对不同化学类别的 35 种农药进行了检测，以评估该概述技术。大多数分析物的回收率在 74-105% 之间，相对标准偏差小于 14%。GC-MS/MS 的线性度、精确度和准确度均符合要求。经过验证的技术有效地应用于农民田里的洋葱样品。
