Research on rapid analysis method of GC-MS/MS for amide and pyrethroidspesticidesinSoil
This study determines the best pre-processing method by optimizing the conditions of the ASE extraction meth-od.By GC-MS/MS determination,a complete set of analysis methods for amide and pyrethroids pesticides in soil was estab-lished.This method can simultaneously detect eight amides and tenpyrethroids pesticide residues in soil.The eight amide pesticides in the range of 1.0-50.0mg/L and the ten pyrethroid pesticides in the range of 10.0-100.0mg/Lhad good lineari-ty.The correlation coefficients were all greater than 0.99.The detection limit of amide pesticides was 3.0-6.1ng/g,and the av-erage recovery rate was 75.0%-83.8%;The detection limit of pyrethroid pesticides was 30.7-73.0ng/g,and the average re-covery rate was 91.8%-102.3%.
