灰岩和白云岩的X射线荧光光谱分析

Analysis of Limestones and Dolomites by X - Ray Fluorescence

摘要:

使用XRF粉末压片法可直接测定灰岩和白云岩中的主要化学成分,对样品进行15min研磨和使用30×102 MPa的制样压力,可以减小基体效应中的粒度效应,再通过数学校正法消除基体效应中的吸收、增强效应,分析结果的准确度和精密度可与化学法相比。

Abstract:

Major chemical compositions of limestone and dolomites can be determined directly by using XRF powder method. Samples have been grinded under 30 x 102 MPa in 15 minutes, thus grain size efficiency can be reduced. Then through maths method to eliminate absorption and strengthen efficiency, results are gained which can compare with the results gained by chemical method.
