摘要
本文用普通X射线荧光光谱仪,结合自编的PEAKFIT谱处理系列软件,对按不同比例配制FeO和Fe2O3混合物的Kβ谱形及谱峰参数进行了研究,用数学方法把实测的谱峰(各价态的重叠峰)分解为各化合态的子谱峰,求出了子峰的面积与总面积的比值,科学地找出了谱峰参数与铁价态的关系。
FeK β emission spectra and parameters of mixtures are studied by conventional XRF spectrometer and PEAKFIT programs.The true spectra profile and it's parameters are obtained by profile resolving method.Integral area ratios are also calculated.The relations of these parameters and the valences of the iron are found.Fe 3O 4 sample and the iron ore which has different valences are quantified.
