摘  要:
[目的]建立番茄中乙撑硫脲和丙撑硫脲残留量的高效液相色谱分析法。[方法]番茄样品用碱性乙腈提取,PSA净化,高效液相色谱测定。[结果]方法的最低检出量为0.038 ng;最低检出质量分数为0.01 mg/kg,乙撑硫脲和丙撑硫脲的平均回收率分别为72.4%~105.5%、72.8%~100.2%,相对标准偏差分别为2.6%~4.9%、3.1%~3.5%。[结论]方法的灵敏度、准确度及精密度符合农药残留分析要求。

摘  要:
[Aims] A method was developed for analysis of ethylenethiourea and propylenethiourea residues in tomato by high performance liquid chromatographic(HPLC).[Methods] The tomato samples were extracted with alkaline acetonitrile,cleaned up by PSA,and determined by HPLC.[Results] The minimum detectable quantity of the method was0.038 ng,and the minimum detectable concentration was 0.01 mg/kg.The average recoveries of ETU and PTU were72.4-105.5 and 72.8-100.2%,the relative standard deviations were 2.6-4.9 and 3.1-3.5%,respectively.[Conclusions] The sensitivity,accuracy and precision of the method met the requirements for pesticide residue analysis.
