X射线荧光光谱法测定长石的化学成分

Chemical Component Analysis of Feldspar by\= Xray Fluorescence Spectrometry

采用粉末压片制样、Ｘ射线荧光光谱仪测定长石的化学组成，可获高准确度和高精密度的分析结果，测定值与化学法及推荐值相符，重复１０次测定主、次量组分的ＲＳＤ＜０．６％，痕量组分ＲＳＤ＜３％。方法简便快捷，分析时间仅为传统湿法化学分析的１／８。

The chemical components of feldspar were analyzed by Xray fluorescence spectrometry with powder pellet sample preparation method. The results provided by this method are in agreement with certified values and with those provided by classical chemical methods. The precision (n=10) of the method is <0.6% RSD for major and minor components and <3% RSD for trace elements. The method is simple, rapid, accurate and precise. The time consumed per sample is only 1/8 of that by classical chemical methods.\=\=
