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10.0pg,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。

关 键 词:全血  RSD  铅接触  石墨炉原子吸收光谱法  儿童  微量铅  工人  相对标准偏差  实验条件  标样

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.
Keywords:Zeeman-GFAAS  Whole blood  Pb
