辉锑矿单矿物中一些微量元素的测定在地质上具有重要意义。要测定这些微量元素,常用的分析方法很难胜任。石墨炉原子吸收法灵敏度高,取样量少,在微量分析中已得到广泛的应用。但是,用石墨炉原子吸收法测定辉锑矿中微量元素的方法目前未见报导。本文用石墨炉原子吸收法测定了辉锑矿中五个微量元素,提出用盐酸挥发除去基体元素锑后测定其中的铅、银、铜的方法;用铜试剂——四氧化碳萃取测定铋的方法;
The determination of some trace elements in stibnite single mineral is of great significance in geology. To determine these trace elements, commonly used analytical methods are not competent. Graphite furnace atomic absorption method has high sensitivity and small sample amount, and has been widely used in microanalysis. However, the method of graphite furnace atomic absorption spectrometry for the determination of trace elements in stibnite has not been reported. In this paper, five trace elements in stibnite were determined by graphite furnace atomic absorption spectrometry. The method for determination of lead, silver and copper in the stibnite by volatilization of hydrochloric acid to remove antimony was proposed. The extraction of bismuth by copper reagent-carbon tetraoxide method;
