摘要 建立了超高效液相色谱-串联质谱联用法测定噻虫胺在马铃薯中的残留量。结果表明:噻虫胺在马铃薯茎秆及块茎中的平均回收率为70%~98%,相对标准偏差为2.8%~9.4%。定量限为0.01 mg/kg。噻虫胺在贵州和黑龙江马铃薯茎秆中的半衰期分别为69.3 d和7.7 d,在贵州和黑龙江马铃薯收获期时噻虫胺的含量分别为0.017 mg/kg和0.025 mg/kg。 A method for the detection of clothianidin residue and its degradation in potato was developed by QuChERS and ultra high-performance liquid chromatography coupled to tandem mass spectrometry(UPLC-MS/MS). The results suggested that the average recovery of clothianidian in stem and potato were ranged from 70%-98%, standard deviations of2.8%-9.4% at spiked levels of 0.01-0.3 mg/kg. The limit of quantification in potato was 0.01 mg/kg. The results in Guizhou and Heilongjiang were showed that the half-life of clothianidin in stem were 69.3 days and 7.7 days, and the final residue in potato at harvest time were 0.017 mg/kg and 0.025 mg/kg in Guizhou and Heilongjiang.
