钢中化学元素的X－射线荧光光谱分析

DETERMINATION OF 15 ELEMENTS IN STEEL BY XRF SPECTROMETRY

本文叙述合金钢中１５种元素的Ｘ射线荧光光谱快速定量分析方法。用Ｘ４０软件中的ＰＨ模式进行共存元素间的谱线重叠和基体吸收－增强效应的校正。对于合金中的微量重元素如Ｃｕ，Ｍｏ，Ｎｂ，Ｗ和Ｎｉ以０．０６５ｎｍ处的散射背景为内标局部补偿样品表面结构、仪器波动和基体效应等因素造成的影响。所得分析结果满足生产要求。

This paper describes XRF rapid analysis of 15 elements in low, medium and high alloy steels by XRF spectrometry and X40 software package.Matrix effects and line overlap interferenec are corrected with PH model.Some of the elements such as Mo,Nb,Cu, W and Ni use scatter background at 0.065urn as internal standard to compensate the matrix effects.The results analysed are satisfactory for production demands.
