Determination of S-metolachlor and Terbutylazine Residues in Soil and Corn by Gas Chromatography-Quadrupole Mass Spectrometry

doi:10.7506/spkx1002-6630-201110038

Abstract

Abstract: An internal standard method for the determination of S-metolachlor and terbutylazine residues in soil and corn by gas chromatography-quadrupole mass spectrometry was developed. S-metolachlor and terbutylazine were extracted with acetonitrile by vortex and cleaned-up with base sorbent (primary secondary amine exchange material- PSA). The recoveries of S-metolachlor and terbutylazine in soil and corn were between 90.4% and 108.5%, and the relative standard deviations (RSDs) were between 1.9% and 5.3%, respectively.

Key words: S-metolachlor, terbutylazine, gas chromatography-mass spectrometry, residue analysis, corn, soil
