熔融制样X射线荧光光谱法测定锰铁合金中硅、锰和磷含量
Determination of Si, Mn and P in Ferromanganese by X-ray Fluorescence by Fusion Method
摘要
用熔融后的四硼酸锂制作铂金坩埚保护层, 以BaO2做氧化剂, 在马弗炉内通过逐渐升温来氧化锰铁合金, 然后熔融制取玻璃熔片, 用X射线荧光(XRF)光谱分析锰铁中硅、锰和磷含量。本法有效消除了锰铁合金熔融制样过程中的坩埚腐蚀问题, 分析误差可完全控制在国家相关标准允许的偏差内, 实现了锰铁合金各元素的快速准确测定。
Abstract
This paper put forward adopting melting lithium tetra borate to make protective layer of Pt-Au crucible, taking BaO2 as the oxidizing agent, oxidating Ferromanganese by increasing the temperature gradually in muffle furnace, making the glass bead by fusion method, and then Si, Mn, P in Ferromanganese were determined by the X-ray fluorescence (XRF) spectrometer. This method resolved the problem of the corrosion of Pt-Au crucible by sample in the fusing process and it’s analytical error could be controlled completely within the acceptable limits from a national standard, proved analyzing the elements in the Ferromanganese quickly and accurately.
