Title: Determination of s- triazine herbicide residues in organic fertilizer by LC- MS / MS
Abstract: 7 kinds of s-triazine herbicide residues in organic fertilizer were simultaneously determined by adopting liquid chromatography-tandem mass spectrometry. These herbicides were extracted from organic fertilizer firstly by using methyl cyanide as the extraction solvent,and then were purified by neutral alumina column.Finally,the sample solvent was analyzed by liquid chromatography-tandem mass spectrometry, and the qualitative and quantitative determination was realized. The test result showed that the limit of quantification of this method was lower than 0. 53 ng / m L. The recovery range was 84. 0% ~ 96. 1% and RSD was 3. 1% ~6. 5%,which were consistent with the requirements in relative standards about pesticide residue detection in China.
