X射线荧光光谱法硅酸盐岩石主次成分的测定的探讨及建议

X-ray Fluorescence Spectrometric Methox Determination of Silicate Rock Major/Minor Composition

国家标准方法《硅酸盐岩石化学分析方法第28部分》已经在硅酸盐岩石分析得到广泛应用。本站在日常工作中发现,对于Al_(2)O_(3)含量较高的高岭土试料分析时,含量较高的组分用国家标准方法检测容易引起误差。本文建议工作中建立空气干燥基和灼烧基两套标准工作曲线,使用灼烧基物料检测来解决样品中Al_(2)O_(3)含量较高时所引起的误差。

State regulatory method Methods for Chemical Analysis of Silicate Rocks-Part 28:has seen wide application in analysis of silicate rocks.The lab discovers that this method is prone to error in the main elements while used to analyze kaolinite rich of Al_(2)O_(3).This study proposes two standard working curves:air dried basis and burned sample basis,in order to address the error in burned sample basis analysis when the sample is rich of Al_(2)O_(3)。
