| Abstract: | Seven kinds of pesticides in water are extracted using fully automated solid-phase extraction(SPE),and tested using gas chromatography/mass spectrometry(GC/MS).The qualitative analysis was performed by retention time and selected ions,and the quantitative analysis was performed by phenanthrene-D10 as internal standard.The results show that the minimum detection limits are 1.0 to 2.4 μg/L,the relative standard deviations are 1.7% to 7.2%,and the recoveries are 82.6% to 92.0%. |
