摘要
A highly sensitive and simple analytical method was developed for analyzing the binary mixed pesticides of prometryne and acetochlor in soil-water system by gas chromatography/mass spectrometry (GC/MS). The sample solution was first purified by C-18 solid-phase extraction column, which was leached by acetone. The leachate was enriched to 1.0mL by pressure blowing concentrator and then analyzed by GC/MS. The linear calibration curves were showed in the range of 1-15g/mL with a correlation coefficient of 0.9991. The average recoveries (n=5) were between 95.3 and 115.7%, with relative standard deviations ranged from 1.71 and 7.95%. The limits of detection of Prometryne/Acetochlor were up to 0.06 and 0.17g/mL, respectively. This method provides a reliable approach to examine and evaluate the residues of prometryne and acetochlor in the soil-water system.
