| | It was shown that the average valence of Fe in minerals is related to the ratio Fe Lβ/Fe Lα. The T FeO and the counting rates of Fe Lβ and Fe Lα of an unknown sample were measured by electron probe. The average valence of Fe was obtained from a correlation curve of Fe L#βFe Lα versus and average valence of Fe which was constructed by using a series of iron-bearing mineralstandards. The contents of Fe(II)and Fe(III)could be calculated from the following equations: | | 研究表明,含铁矿物中铁的平均价态(反映Fe~(2+)和Fe~(3+)含量)与Fe Lβ/Fe Lα值呈正比关系曲线。未知样品只要测得TFeO含量和Fe Lβ、Fe Lα的计数值,就可以分别获得FeO和Fe_2O_3的定量分析结果。经几种含铁矿物测定实例验证,说明方法可行。 | | 文摘来源 | |   |
