中文摘要：本文提出了一个检测谷物中23种不同类农药（有机氯和有机磷化合物，拟除虫菊酯类和三唑类杀菌剂）残留的方法。该检测方法首先采用QuEChERS方法进行样本制备，然后使用天然铝硅酸盐进行提取物清晰，最后采用气相色谱串联质谱法进行检测。检测结果显示，定量限为0.005 mg/kg，相对标准偏差不超过0.02，分析时长为35-40分钟。
 
 
外文摘要：A procedure for the determination of 23 pesticides from different classes (organophosphorus and organochlorine compounds, synthetic pyrethroids, and triazoles) in cereal crops is proposed. It is based on sample preparation according to the QuEChERS method with the subsequent cleaning of the extract with natural aluminosilicate and the determination of analytes by gas chromatography with mass-spectrometric detection. The limits of the quantitative determination of pesticides are similar to 0.005 mg/kg. The relative standard deviation does not exceed 0.02. The duration of analysis is 35-40 min.
