摘要
【目的】探讨一套能够高效、准确同时检测蔬菜中乙酰甲胺磷和甲胺磷的方法。[方法]通过对氮吹浓缩温度、进样口条件、升温程序等方面进行控制和优化，并采用空白基质匹配标准溶液的方法，建立能够高效、准确同时检测蔬菜中乙酰甲胺磷和甲胺磷的方法。【结果】所建立的方法检测蔬菜中乙酰甲胺磷和甲胺磷舍量，检出限为0．007-0.010mg／L；方法的回收率为83．9％-102．5％，相对标准偏差为2．4％-4．3％。[结论】建立的蔬菜中乙酰甲胺磷和甲胺磷检测方法高效、准确，可用于实践。
[Objective]The aim was to explore a method for simultaneous effi- ciently and accurately detecting acephate and methamidophos in vegetables. [Method] The method for simultaneous efficiently and accurately detecting acephate and methamidophos in vegeta- bles was found, by controlling and opti- mizing concentrate temperature of nitro- gen blow, inlet conditions, temperature program and others, and using blank ma- trixmatched standard solution method. [Result] The limit of method for detecting acephate and methamidophos in vegeta- bles was 0.007--0.010 mg/L, with the re- covery of 83.9% -102.5%,and the rela- tive standard deviation of 2.4%-4.3% . [Conclusion ] The method for detecting acephate and methamidophos in vegeta- bles was efficient and accurate, so it could be used in practice.
