氢化物发生-原子荧光光度法同时测定钨精矿的砷、锑

Determination of Arsenic & Antimony Contents in Tungsten Concentrates by Hydride Generation and Atomic Fluorescence Spectrometry

探讨了氢化物发生-原子荧光光度法同时测定钨精矿中的砷、锑的可行性。提出了3种试样消解方法,并对其进行了比较。选择了最佳测定条件,并对干扰元素进行了分析研究。

This paper studies the simultaneous determination of arsenic ＆ antimony contents in tungsten concentrates by hydride generation atomic fluorescence spectrometry. Three kinds of digestion methods are proposed ＆ compared. The optimum parameters for detection ＆ interference elements are decided. The results indicate this method is characterized by high-efficiency, high-precision, favorable stability and easy operation.
