QuEChERS/液质联用法测定干制水果中多种农药残留
Determination of Multiple Pesticide Residues in Dried Fruits by QuEChERS/LCMS
摘要
Abstract
In order to rapidly and accurately determine multiple pesticide residues in dried fruits,this study optimized a pretreatment method that can effectively extract and purify multiple pesticide residues in samples.Six pesticidesin dried fruits were simultaneously determined by liquid chromatography-tandem mass spectrometry.The test results showed that the limits of quantification for various pesticides ranged from 0.07 to 0.90 μg/L.The recovery rate of adding pesticides to dried strawberries was 78.0%～93.3%,with relative standard deviations(RSD)of 1.7%～6.4%.Meanwhile,this method was also applicable to the detection of pesticide residues in various other dried fruits.The recovery rate in dried kiwifruits was 81.0%～89.4%,with RSD of 2.4%～6.6%;in dried apples,the recovery rate was 77.0%～91.2%,with RSD of 1.9%～6.8%;and in dried bananas,the recovery rate was77.6%～89.5%,with RSD of 2.2%～6.2%.关键词
