| 摘 要： | 采用石英缝管装置，辅助火焰原子吸收光谱法测定了食醋中的痕量铅。对铅的测量灵敏度较常规火焰原子吸收法提高了4倍以上。装置简单，方法简便，有效地降低了对测量灵敏度较低的组分的富集要求，提高了分析结果的可靠性。

| Abstract: | The concentration of trace lead in vinegar was determined by flame atomic absorption spectrometry equipped a set of slotted quartz tube.The sensitivity of this method was improved more than 4 times comparing with ordinary flame atomic adsorption spectrometry.It is rapid and convenient with a sample setting.The reliability of results obtained has been enhanced for no necessary of enriching desired constituent with low response sensitivity. |
