摘要
[目的]为建立一套快速、简单、准确的有机磷残留量检测方法。[方法]建立了使用超声波强化萃取-氢火焰离子化检测器气相色谱法（FID／GC）检测甘蔗中甲拌磷、特丁硫磷残留量的方法。[结果]当甲拌磷的浓度为0．80～3．20μg／ml，特丁硫磷的浓度为0．96～3．20μg／ml时，它们的浓度与峰面积呈良好的线性关系；样品加标平均回收率为81．58％～84．77％，相对标准偏差（RSD）为4．69％～6．68％。[结论]FID／GC方法操作简便，能满足农药残留量的分析要求：
[ Objective] The study aimed to establish a rapid, brief, accurate method to detect organophosphorus residues. [ Method] The method of FID/GC to detect phorate and terbufos in sugarcane were established. [ Result ] Concentration of phorate and terbufos and peak area showed a good linear relationship concentration when the phorate concentration was 0.80 - 3.20 μg/ml and terbufos concentration was 0. 96 - 3.20μg/ml; recovery of standard addition was 81.58% - 84.77% , RSD was 4.69% - 6.68%. [ Conclusion ] Method of FID/GC easy to operate, and which can satisfy the requirements of residues analysis.
