氢化物发生-原子荧光光谱法则定锑精矿中的微量砷

使用氢化物发生—原子荧光光谱法测定锑精矿中的微量砷在国内外报道较少。文章在锑干扰状况试验、高锰酸钾溶液消除干扰的最佳条件选择试验、锑精矿中共存元素的干扰和消除试验的基础上,对样品进行了实测,并就其灵敏度、准确度和精密度进行了讨论。研究表明,该方法是测定锑精矿中微量砷的有效方法。

Determination of trace arsenic in antimony concentrate by hydride generation-atomic fluorescence spectrometry

Few report has been made at home and abroad about the using of the HG-AFS method to determine the trace arsenic of antimony concetrate. Based on the experiment of antimony interference, the experiment of choosing best condition by using KMnO4 solution to eliminate the interference, as well as the experiment of elminating the interference of coexisting elements in antimony concentrate, it has tested the samples with the discussion about the sensitivity, accuracy and precision of this method. The research has shown that the HG-AFS method is an effective method of determining trace arsenic in antimony concentrate.
