利用X荧光能谱仪快速测定合金钢中钛元素

Rapid analysis of titanium in ferroalloy by X-ray fluorescence energy spectrometer

在合金钢能量色散X射线荧光光谱的研究基础上,使用国产的XRF-6型X射线荧光能谱仪对合金钢中钛元素进行了分析技术研究。钛元素的Kα特征射线能量值为4.51keV,与特征能量值为4.66keV的FeKα逃逸峰叠加重合,严重干扰钛元素的测定。研究了铁元素逃逸峰干扰的快速扣除方法,得到FeKα峰比例扣除、FeKα逃逸峰高能侧对称扣除法和TiKα峰低能侧对称积分法等快捷处理方法。工作曲线的制作和实际样品测定结果证明几种快速分析方法是可靠准确的。

In this paper, the FeKaescape peak interference quick deduction method was studied. The FeKa peak proportional deductions, FeKoescape peak high-energy symmetric deduction method and low-en- ergy TiKo peak symmetric integral method were got. Work curve of the production and the actual sample measurement results show that these rapid analysis methods are reliable and accurate.
