全自动原子荧光法测定煤中汞含量的影响因素研究

Study on factors affecting determination of mercury in coal by automatic Atomic Fluorescence Spectrometry method

试验研究了全自动原子荧光法测定煤中Hg含量的影响因素;煤样量的多少对测定结果没有影响,受Hg污染的王水以及受到污染的煤样对测定结果有影响;建议在干净清洁的环境中进行实验,以防止含Hg物质的污染,从而提高测定结果的准确度。

The impact factors of Hg content determination of coal by automatic atomic fluorescence spectrometry method were studied. The results showed that the amount of coal sample had no effect on the determination result,but contaminated aqua regia or coal by mercury had effect on the determination results. It is suggested that keeping the environment clean and dry to prevent Hg- containing substances form polluting could improve the accuracy of the determination results.
