【摘要】 蔬菜样品用乙腈提取,固相萃取后浓缩,采用气相色谱法测定了添加样品中异菌脲的残留量。测定结果表明：异菌脲的浓度范围在0．1～1．0μg/mL 内,其峰面积与进样质量的线性相关系数为 0．9950,其回收率为75．9%～101．4%,相对标准偏差 RSD%(n=6)在5．42%～7．78%之间,检出限为0．001 mg/kg。该法具有灵敏、准确,前处理简单易行等优点。更多还原

【Abstract】 The iprodione was extracted from the vegetable samples by acetonitrile,and then cleanup by solid phase extraction.Gas chromatography was used to determine the iprodione residue in the vegetable. The result of determination showed that there was a good linear calibration curve in the range from 0.1 to 1.0μg/mL.The average recovery for the determination were in the range of 75.9%-101.4%.The relative standard deviations of samples were from 5.42% to 7.78%(n=6).The limit of detection of this method was 0.001 mg/kg.The method is simple,sensitive,accurate and reproducible.更多还原
