| 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%。

Determination of gold in selenium-containing materials by FAAS |
| |
| Abstract: | An analytical method for the determination of gold in selenium-containing materials by FAAS was es-tablished.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 re-covery by addition method was in the range from 95.0 %to 103.5 %,and the RSD from 1.0 %to 3.3 %. |
