摘要
试样经火试金富集,稀硝酸,王水分解,用火焰原子吸收光谱法测定金,克服了试样经650℃灼烧王水溶解活性炭吸附原子吸收光谱法测定带来结果不稳定,精密度差返工率高等不足,缩短了分析时间,方法经国家一级标准物质验证结果与标准相符。
The samples were treated troμgh preconcentration by fire assay and decomposition by dilute nitric acid, aqua regia, and the content of gold was determined by flame atomic absorption spectrometry, it was overcome that the unstable results of samples that were fired under 650℃, dissolved by aqua regia and absorbed by activated carbon were determined by flame atomic absorption spectrometry,and reworked rate higher of precision difference was also overcome, the analysis time was shortened. The method is validated by the state material standard, and the results matched with the standard values.
