摘要
研究建立了火试金富集—原子吸收光谱法测定含硒物料中金的方法。样品挥发除硒处理后经火试金法富集得到金银合粒,分金后金粒用王水溶解,且在王水介质中采用原子吸收光谱仪测定。该方法相对标准偏差为1.0%-3.3%,加入标准物质回收率为95.0%-103.5%。
An analytical method for the determination of gold in selenium-containing materials by FAAS was established. Samples were enriched by fire assay after the volatilization of selenium. Gold particles were dissolved by aqua regia. The gold concentration was determined by atomic absorption spectrometry in aqua regia medium. The recovery by addition method was in the range from 95. 0 % to 103. 5 %,and the RSD from 1. 0 % to 3. 3 %.
