摘要:

本实验建立了一种水果中常见有机磷农药的快速残留测定方法。试样中残留农药用乙腈超声波振荡提取,气相色谱- 火焰光度检测器测定。19 种有机磷农药的添加浓度在0.05~1.5mg/kg 时,苹果中的平均回收率为73.4%~123.0%,相对标准偏差为0.34%~12.59%;方法的检测限LODs 范围为1.0~5.0μg/L,LOQs 范围为3.3~16.7μg/kg,该方法符合农药多残留分析要求。

Abstract:

A rapid method was developed for the determination of 19 organophosphorus pesticides in apples. The sample was firstly extracted by ultrasonic with acetonitrile, and then the extracts were concentrated with rotary evaporator and determined by gas chromatography equipped with Flame Photometric Detector. The results showed that when the additive level of 19 organophosphorus pesticides is 0.05 mg/kg to 1.5 mg/kg, their average recoveries from apples are 73.4% to 123% with the relative standard deviation (RSD) of 0.34% to12.59%, the limits of detection (LODs) are 1.0 μg/L to 5.0 μg/L, and the limits of quantification (LQDs) are 3.3 μg/kg. This developed method can be used to determine organophosphorus pesticides in commercial fruit samples.

Key words: gas chromatography, organophosphorous pesticides, apple, residue analysis method
