QuEChERS-气相色谱-三重四极杆串联质谱法测定土壤中33种农药残留
Determination of 33 pesticides residues in soil by QuEChERS-GC-MS/MS
摘要
Abstract
The QuEChERS method is optimized to extract pesticide residues from frozen-drying soil samples,including 24 organochlorine pesticides(OCPs)and 8 organophosphorus pesticides(OPPs)as well as atrazine.An approach to simultaneous determination of 33 pesticide residues in soil is established by combining with gas chromatography-tandem mass spectrometry(GC-MS/MS).The results show that the concentration of 33 pesticide residues is 5.0-100 μg/L,in good linearity,with method limit of detection(LOD)0.09×10-9-0.52×10-9,limit of quantitation(LOQ)0.30×10-9-1.71×10-9,relative standard deviation(RSD)of precision 3.7%-17.2%,and recovery 51.6%-118.8%.The method is simple and rapid,characterized by high recovery and sensitivity,and strong resistance to matrix interference,which is suitable for trace analysis and detection of OCPs and OPPs in soil.关键词
