Determination of Elements in Stainless Steel by X-Ray Fluorescence Spectrometry
-
摘要: 采用X射线荧光光谱固体法测定不锈钢中主次成分元素的含量,并对各元素间的谱线重叠、基体效应等影响因素进行了干扰校正。通过精密度测试和对比试验表明,对于主成分元素(Cr、Ni、Si、Mn、Ti、Mo、W),方法的相对标准偏差(RSD)小于1%,对于微量成分元素(Al、Cu、Co、Sn),方法的RSD小于12%。Abstract: Various elements in stainless steel have been measured by X-ray fluorescence spectrometry. Spectral overlap and matrix effect of interference elements have been corrected by interfering. The precision and comparative tests show that the precision of the method（RSD） is less than 1% for the main portions of elements（Cr, Ni, Si, Mn, Ti, Mo, W）, and the precision of the method（RSD） is less than 12% for the trace elements（Al, Cu, Co, Sn）.
