【摘要】 以双电极高强度空心阴极灯作激发光源，于铁氰化钾碱性体系内进行铅的氢化反应。实验表明，原子化过程中石英炉芯对铅烷存在吸附。在最佳测试条件下，溶液检出限为０．１７ μｇ／Ｌ，分析了国家一级植物标样和头发标样中痕量铅，取得令人满意的结果。更多还原

【Abstract】 Lead hydride was resulting from the merging of an acidifide sample solution with potassium tetrahydroborate reduction solution containing potassium ferricyanide. Expeti- ment results showed that some PbH2, was adsorbed by quartz surface of atomizer. Detection limit of the method was 0. 17 μg/L and satisfied results were obtained in the analysis of four national primary reference materials of vegetation and human hair.更多还原
