火焰原子吸收光谱法测定载金炭中金

Determination of gold in gold-loaded carbon by flame atomic absorption spectrometry

采用火焰原子吸收光谱法测定了载金炭中的金,并经过方法条件实验,确定了最佳测定条件。该方法相对标准偏差为0.37%～1.01%,加入标准物质回收率为100.4%～102.7%。该方法与经典火试金法对比,测定结果完全符合。

This article discusses a method of flame atomic absorption spectrometry for determination of gold in gold-loaded carbon. Through method designation and condition testing, the best determination conditions were settled. The relative standard deviation of this method is 0.37 % - 1.01%, and the recovery ratio is between 100.4 % - 102.7 % when reference materials are added. The results of this method are consistent with the results measured by classical fire assay method.
