中文摘要：本文开发了一种柑桔中四种杀菌剂（噻菌灵，抑霉唑，邻苯基苯酚、苯）残留的简单检测方法。使用大气压电离接口的液相色谱-串联质谱对化合物进行检测，杀菌剂回收率在92%-114 %范围内，相对标准差小于10%。采用休哈特控制图进行评估显示所有数据点均在控制区域内，证明了该方法在对柑桔中四种杀菌剂定量检测方面具有一定的稳健性。此外，检测十个样品的准备时间只需2个小时左右，突出了该方法在时间和劳动效率方面的优势。
外文摘要：A simple method for the determination of four fungicides (thiabendazole, imazalil, o-phenylphenol, and diphenyl) in citrus fruits has been developed. After spiking surrogates of these fungicides, the sample was extracted with acetonitrile, salted out, and the water was simultaneously removed using anhydrous magnesium sulfate and sodium chloride. The extract was first purified with a primary secondary amine and octadecylsilane, followed by the addition of dimethyl sulfoxide as a keeper solvent, and subsequently concentrated under a nitrogen stream. The compounds were analyzed by liquid chromatography-tandem mass spectrometry using the atmospheric pressure photoionization interface. The recoveries and relative standard deviations (RSDs) of the fungicides (1 mg kg(-1)) were satisfactory (recovery 92-114 %; RSD < 10 %). An evaluation with Shewhart QC plots revealed that all data points are within the controlled area, thus confirming the robustness of the method for analyzing the fungicide content of citrus fruits. The sample preparation time for ten samples was approximately 2 h, highlighting the time and labor efficiency of the method.
