| 摘 要： | 为明确烯酰吗啉在土壤及番茄中的残留状况，建立了气相色谱测定土壤和番茄中烯酰吗啉残留量的分析方法。样品用乙腈振荡提取，再用乙酸乙酯萃取，经中性氧化铝层析柱净化后，通过火焰离子化检测器检测，外标法定量。结果表明：在0．5～15mg／L范围内，烯酰吗啉的峰面积与其质量浓度间呈良好的线性关系，相关系数为0．9996。在添加水平为0．5～5．0mg／kg范围内，土壤和番茄中烯酰吗啉平均回收率分别为85．4％～92．7％、89．8％-99．3％，相对标准偏差分别为1．61％～6．59％和1．62％～2．32％。经检测，烯酰吗啉在番茄上的残留量未超过韩国最高残留限量标准。

| Abstract: | In order to investigated the current status of dimethomorph residues, the dimethomorph residues of soil and tomato were quantified by gas chromatography （GC） with flame ionization detector （FID）. The samples were extracted using acetonitrile, and purified by ethyl acetate, then cleaned up by neutral alumina and determined by FID. The results showed that the linear ranges were 0. 5 - 15 mg/L with the linear correlation coefficient of 0. 099 96. When dimethomorph was spiked at 0.5 - 5.0 mg/kg level, the average fortification recovery of soil and tomato were 85.4% -92.7% and 89.8% - 99.3% , and relative standard deviation of 1.61% -6.59% and 1.62% - 2.32% , respectively. The final residues of dimethomorph in tomato were lower than the MRL of Korea. |
