| Abstract: | A method was established to determine trace lead in wheat flour by hydride generation atomic fluorescence spectrometry. In trhis way,the linear ranger was 0 ~ 40 ng / m L,RSD was 1. 9%,limit of detection was 0. 029 ng / m L,recovery of sample was 94. 5% ~ 102%. The method was simple,fast,high sensitive,repeatable. |
