| Abstract: | In this paper the optimized conditions of enriching trace plumbum in water on a cylinder of dithizone activated carbon are researched. The recoveries of plumbum were determined in different enrichment conditions by flame atomic absorption spectrometry. The interference of several metal ions was discussed. |
