摘要: An analytical method based on ultra performance liquid chromatography. tandem mass spectrometry was developed for the determination of SIOC0426 residues in environment samples (soil, sediment and water). The fate of SIOC0426 in three kinds of soils was also evaluated. The target compound was extracted with acetonitrile, cleaned up by C-18 cartridge, and analyzed by gradient ultra performance liquid chromatography. tandem mass spectrometry with electrospray ionization under positive mode (ESI+) using a UPLC BEH C-18 column. The method was validated using fortified soil, sediment and water. Mean recoveries of SIOC0426 at three spiked levels (0. 005, 0. 05 and 2. 0 mg/kg) ranged from 87% to 106% with relative standard deviations of 2. 8% -8. 0%. Limits of quantification (LOQs) of SIOC0426 in soil (sediment) and water were 0. 2. mu g/kg and 0. 2. mu g/L, respectively. Linear calibration functions with correlation coefficients R-2>0. 9999 were obtained in the concentration range of 0. 5 - 20 mu g/L. This method was applied to the analysis of SIOC0426 residues in soil degradation samples. The results showed that the half. life of SIOC0426 ranged from 1. 72 days to 28. 2 days in three kinds of soils under aerobiotic conditions. While, the half. life of SIOC0426 ranged from 2. 93 days to 31. 4 days in three kinds of soils under anaerobic conditions. The degradation speed of SIOC0426 under aerobiotic conditions was faster than that under anaerobic conditions in the same soil. And the degradation speed of SIOC0426 in soils may be connected with the pH value of soils, cation exchange capacity and soil texture.
