摘　　要：采用无机酸、表面活性剂、无机盐以及有机酸作为增敏剂对火焰原子吸收法测铅元素吸光度的增敏效应进行试验,得出0.80%硝酸铜在同等条件下对铅的增敏效果最好的结论,并借此探讨各增敏剂的增敏机理.The hydrochloric acids, surfactants, inorganic salt and Organic acids were utilized as sensitizers in the enhancement effect of Pb measured by flame atomic absorption spectrometry experiment. The results showed that： the 0.80% copper nitrate had a largest radio sensitizing effect at the same work-condition compared with other substances. The mechanism of enhancing effect of each sensitizers had been discussed.
