摘　　要：建立了测定面粉中微量铅的氢化物发生-原子荧光光度法。在实验条件下,铅的线性范围为0~40 ng/m L,测定精密度为1.9%,检出限为0.029 ng/m L,样品加标回收率在94.5%~102%之间。该方法简单、快速、灵敏度高、重现性好。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 N 40 ng/mL, RSD was 1.9%, limit of detection was 0. 029 ng/mL,recovery of sample was 94. 5% N 102%. The method was simple, fast, high sensitive, repeatable.
