ARL9900X荧光压片法测定煤灰中K_(2)O、Na_(2)O等元素

Determination of K_(2)O,Na_(2)O and Other Elements in Coal Ash by ARL9900X Fluorescence Spectrometer and Tablet-Pressing Method

本文主要介绍用ARL9000X荧光压片法测定煤灰中K_(2)0、Na_(2)0、Al_(2)O_(3)、CaO、Fe,03MgO、TiO_(2)等元素,制定样品制备流程,建立工作分析曲线,实验确定仪器工作条件、制样条件,对曲线干扰进行消除校正,元素测定的精密度、准确度均达到分析标准要求。

The determination of K_(2)O,Na_(2)O,Al_(2)O_(3),CaO,Fe_(2)O_(3),MgO,TiO_(2) and other elements in coal ash by ARL9000X fluorescence spectrometer and tablet-pressing method is introduced in this article.The sample preparation process is made.The working analysis curve is established.The working conditions of the instrument and the sample preparation conditions are determined experimentally.The interference of the curve is eliminated and corrected.The precision and accuracy of element determination meet the requirements of the standard.
