摘  要:
[目的]针对土壤中杀菌剂戊菌唑残留的检测,建立具有经济、环保等特点的快速可靠的分析方法。[方法]建立2种分析方法:柱色谱-超高效液相色谱法(CC-UPLC)和浊点萃取-超高效液相色谱法(CPE-UPLC)。[结果]经CC-UPLC和CPE-UPLC法处理,土壤样品戊菌唑的平均添加回收率分别为89.7%~102.4%、90.6%~94.8%;相对标准偏差分别为1.7%~6.1%、1.7%~3.0%;最低检出限分别为2.0、0.8滋g/kg。[结论]2种方法均能满足农药残留检测的要求,与CC-UPLC法相比,CPE-UPLC具有更好的准确度及灵敏度,符合绿色化学的发展趋势,是一种值得推荐的检测方法。

摘  要:
[Aims] The aims were to develop economical, environmentally-friendly, fast and reliable determination method for penconazole residues in soil. [Methods] Column chromatography-ultra performance liquid chromatography(CC-UPLC) and cloud point extraction-ultra performance liquid chromatography(CPE-UPLC)methods were developed for the determination of penconazole residues in soil. [Results] The average recoveries of penconazole at the three spiked levels by using CC-UPLC ranged from 89.7 to 102.4%, with the relative standard deviations(RSD) of 1.7-6.1%,and the limit of detection was 2.0 滋g/kg. The average recoveries of penconazole detected by CPE-UPLC ranged from90.6 to 94.8%, with the relative standard deviations(RSD) of 1.7-3.0%, and the limit of detection was 0.8 滋g/L.[Conclusions] Both methods have proven to be efficient for pesticide residues detection. However, compared with CC-UPLC, CPE-UPLC should be more worthy of recommendation, in virtue of its environmental-friendly, time-saving,efficient, easy operating and inexpensive.
