摘要
对固相萃取前处理条件及色谱条件进行优化,实现对6种芳香胺的富集、分离与检测。建立6种组分的工作曲线,检出限为0.0004~0.0007 g/mL(S/N=3),样品加标平均回收率为92.5%~103%,相对标准偏为4.9%~6.1%。
The six components can be enriched and deceted under the optimal SPE and GC conditions.The working curves were obtained.The detection limits were in the range of 0.0004~0.001 g/mL(S/N=3).The average recoveries of samples were 92.5 %~103 % and the relative standard deviations were 3.4 %~4.9 %.
