| 摘 要： | 提出用0.5%硝酸稀释样品，Zeeman-石墨炉原子吸收光谱法直接测定全血中微量铅，并讨论了有关的实验条件。方法的检出限为10.0 pg，标样的相对标准偏差(RSD)0.36％～1.8％，样品的相对标准偏差(RSD)1.4％～2.3％，回收率96.0％～101.7％，共存物干扰小。利用此法已分析600多例铅接触工人和儿童，结果满意。本法简单，快速是一种理想的全血测定方法。

| Abstract: | The determination method for trace Pb in whole blood was studied, which was diluted by 0.5% HNO_3. In the measurement, Zeeman-GFAAS was used and the relative condition was discussed. This method shows that the detection limit was 10.0 pg, the relative standard deviation of standards (RSD) was 0.36%-1.8%, the relative standard deviation of samples (RSD) was 1.4%-2.3%, and the recovery rate was 96.0%-101.7%. The concurrent interference was low. This method is simple and rapid. It is an ideal method to determine trace Pb in whole blood. |
