ICP-AES原子发射光谱法测定硅铁中的钛和铜

Determination of Titanium and Copper in Ferrosilicon by ICP-AES Atomic Emission Spectrometry

探讨了使用ICP—AES原子发射光谱法测定硅铁中钛和铜的新方法。试样用硝酸、氢氟酸分解，高氧酸冒烟除硅和过量氢氟酸，导入ICP—AES原子发射光谱仪中进行测定。通过进行准确度和精密度试验，证明新方法简单、快速、准确可靠，可以满足生产及科研检验需求。

The new method for the determination of titanium and copper in ferrosilicon by ICP-AES atomic emission spectrometry was discussed. The sample was decomposed with nitric acid and hydrofluoric acid, the silicon and excessive hydrofluoric acid were eliminated by smoking with perchloric acid, then, the test solution was guided into ICP-AES atomic emission spectrometry to carry out the determination. Through accuracy and precision testing, it was proved that, the new method was simple, rapid, accurate and reliable, could meet the demands of production and scientific research.
