| Abstract: | 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. |
