| Abstract: | Non standard determination of lead in beryllium oxide by Zeeman graphite furnace atomic absorption spectrometry was introduced. Mg(NO 3) 2 and Ascorbic acid were used as a mixed matrix modifier to eliminate the interference. The relative standard deviation was less than 5%.Recovery rate of standard additions method was satisfactory. |
