摘要
Abstract
To enhance the detection efficiency of carbamate pesticide residues in tomatoes by liquid chromatography,this study established a high-performance liquid chromatography detection method integrating QuEChERS with solvent re-dissolution and purification.Samples were ex-tracted with acetonitrile,purified by QuEChERS,blown to near-dryness with nitrogen,and then re-dissolved in a methanol-water mixture for analysis.The accuracy and reliability of the method were evaluated through spiked recovery experiments.The results indicated that the recovery rates of 10 carbamate pesticides ranged from 61.0%to 104.6%,and the relative standard deviations(RSDs)were between 0.3%and 7.7%.This method is easy to operate and rapid in detection,and can meet the requirements for detecting 10 carbamate pesticide residues in Vegeta-bles.关键词
