甘蔗经加速溶剂萃取仪萃取,应用气相色谱仪定量法检测乐果和特丁磷,建立了定量检测甘蔗中乐果和特丁磷的快速、准确、高灵敏度的方法。经方法学验证,该方法对乐果最低检出限（LOD）为0.01 mg/kg,特丁磷LOD为0.05 mg/kg。乐果和特丁磷在1.0～100.0μg/mL的线性范围内,相关系数r〉0.999 9。乐果回收率为91.5%～99.6%,相对标准偏差（RSD）为1.9%～3.2%,特丁磷回收率为81.0%～93.2%,RSD为2.0%～3.5%。结果表明,该检测方法灵敏度高、操作简单、定量准确、测定浓度范围广,是甘蔗样品中乐果和特丁磷含量检测的理想方法。

Extraction of sugar cane by accelerated solvent extraction（ASE）,and determination of dimethoate and Terbufos by gas chromatography（GC）,which was fast,accurate and highly sensitive method.The limit of detection（LOD） for dimethoate was 0.01 mg/kg,and Terbufos was 0.05 mg/kg.The linear range was 1.0～100.0 μg/mL with correlation coefficient above 0.999 9.The recovery of dimethoate was between 91.5% and 99.6%;Relative standard deviation（RSD） was between 1.9% and 3.2%.The recovery of Terbufos was between 81.0% and 93.2%;RSD was between 2.0% and 3.5%.This method can be applied for the determination of dimethoate and Terbufos in sugar cane for its high sensitivity and high selectivity.
