X荧光光谱法测定碳酸盐型石墨中除碳外的9种主要组成元素

Determination of 9 major components in carbonate type graphite by X fluorescence spectrometry

碳酸盐型石墨在高温分解后的灰分使用四硼酸锂+偏硼酸锂混合熔剂熔融制成玻璃熔片,采用X荧光光谱仪直接测试Si、Ca、Mn、Mg、Ti、K、Na、Al、Fe 9种成份。该分析方法具有检测范围广,精密度、准确度高的优点,适应于碳酸盐型石墨的分析。

The high-temperature decomposed ash from carbon graphite was melt to glass by lithium tetrabo-rate＋lithium metaborate. Nine elements were detected by X fluorescence spectrometer. The analytical method has the advantages of wide detection range, high precision and high accuracy, which is suitable for the analysis of car-bonate type graphite.
