Studies on the methods for AAS determination of trace gold in mineral samples

对采用原子吸收光谱法测定矿石中微量金的方法进行了探讨 ,改进了样品前处理方法 ,并总结出仪器最佳的工作条件 ,提高了分析结果的准确度 .用标准试样验证 。

Methods for AAS determination of trace gold in mineral samples have been researched in this paper. The methods for dealing with samples and conditions of AAS operation have also been improved. More accurate analytical results can be obtained by this new methods. The methods have been evaluated by determination of trace gold in standard samples and the results are in agreement with standard samples.
