QuEChERS-气相色谱法测定牛奶中24种有机氯及菊酯类农药残留
Determination of 24 Organochlorine and Pyrethroid Pesticide Residues in Milk by Modified QuEChERS Method and Gas Chromatography
摘要
Abstract
In this study, a modified quick, easy, cheap, effective, rugged and safe (QuEChERS ) approach was applied for the determination of 24 organochlorine pesticide and pyrethroid residues in milk samples by gas chromatography-electron capture detector (GC-ECD). Milk samples were extracted with acetonitrile, purified with the modified QuEChERS approach, and detected by GC-ECD. The external standard method was used for quantification. Excellent linearities were achieved for all target analytes in the range of 5–250μg/L with correlation coefficients greater than 0.99. The limits of detection (LODs) ranged from 0.06 to 0.30 µg/kg. The recoveries were in the range of 85.5%–111.2%, with relative standard deviations (RSDs) less than 11%. In summary, the proposed method was simple, accurate, efficient and adequate for the rapid screening and quantitative analysis of organochlorine pesticide and pyrethroid residues in milk.关键词
