摘要
Abstract
QuEChERS method was used in pretreatment, and 10 kinds of organophosphorus pesticide residues in mango samples were detected by triple quadrupole GC-MS.The accuracy and feasibility of the method were determined by linear relationship, relative standard deviation and addition recovery rate.The linear correlation coefficient R of 10 organophosphorus pesticides in the range of 0.01-0.40 mg/L is greater than 0.996, and the linear relationship is good.The relative standard deviation of 10 organophosphorus pesticides in 0.04 mg/L mixed standard so-lution is 1.44％-4.10％, which meets the detection requirements.The average recovery rate of 10 organophosphorus pesticides was 75.00-112.50％ when the mixed standard solution with the concentration of 0.02, 0.04, 0.08, 0.16 and 0.32 mg/L was added.The results show that the method is accurate in qualitative analysis and simple in operation, and it is suitable for the daily detection of organophosphorus pesti-cide residues in mango samples.关键词
