| Abstract: | Used as an experimental subject,liquor was tested for its Pb and Mn by continuum source atomic absorption spectrometry.With direct digestion of nitric acid and concentration,the simultaneous determination of Pb and Mn could reduce reagent error and was simpler than the national standard.The recovery rate was between 96.0% and 105.0 % with the RSD of the method and test precision under 5.0 %（n = 5）. |
