气相色谱法在果蔬有机磷农药残留检测中的应用

Application of Gas Chromatography in the Detection of Organophosphorus Pesticide Residues in Fruits and Vegetables

随着现代农业的发展,有机磷农药在果蔬生产中得到广泛应用,但这也导致农药残留问题愈发凸显。本文探讨气相色谱法在检测果蔬有机磷农药残留中的应用现状,并分析其基本原理及主要优势。通过对基质干扰、热不稳定性以及检测灵敏度不足等问题的分析,提出优化样品前处理、改进进样口设计、采用高灵敏度检测器等有效对策。总之,气相色谱法在果蔬有机磷农药残留检测中的准确性和可靠性较高,具有重要的应用价值。

With the development of modern agriculture,organophosphorus pesticides are widely used in fruit and vegetable production,but this also leads to the problem of pesticide residues.This paper discusses the application of gas chromatography in the detection of organophosphorus pesticide residues in fruits and vegetables,and analyzes its basic principle and main advantages.Based on the analysis of matrix interference,thermal instability and insufficient sensitivity,some effective measures such as optimizing sample pretreatment,improving inlet design and adopting high sensitivity detector are put forward.In short,the accuracy and reliability of gas chromatography in the detection of organophosphorus pesticide residues in fruits and vegetables are high,and it has important application value.
