气相色谱法测定稻谷中啶虫脒农药残留的研究

Determination of Acetamiprid Pesticide Residues in Rice by Gas Chromoltography

啶虫脒农药残留是稻谷中的重要污染物，采取有效措施来预防和消除啶虫脒农药污染具有重要的现实意义。研究啶虫脒在粮谷中的残留量分析方法，利用气相色谱火焰离子化检测器对其进行检测，实验可得，样品回收率为82．23％~93．07％，相对标准偏差为1．88％～2．72％。此方法的稳定性高，重现性好，可广泛应用于稻谷中的农药残留量检测。

Acetamiprid pesticide residues are important pollutants in the paddy,take effective measures to prevent and has important practical significance to eliminate acetamiprid pesticide pollution.This research is the analysis method of acetamiprid residues in cereals.By using gas chromatography with flame ionization detector to detect, experiment, sample recovery rate from 82.23%-93.07%,the relative standard deviation is 1.88%-2.72%.This method has the advantages of high stability, good reproducibility, which can be widely used in rice pesticide residues in the detection of rice.
