固体回收燃料X射线荧光法测定元素组成

[中文适用范围]： 本文件规定了通过能量色散 X 射线荧光 (EDXRF) 光谱法或波长色散 X 射线荧光 (WDXRF) 光谱法使用固体回收燃料进行校准来测定固体回收燃料材料中主要和微量元素浓度的程序参考材料或已知含量的固体回收燃料样品。 可以使用与基质无关的标准品进行半定量测定。 本文件适用于以下元素：Na、Mg、Al、Si、P、S、Cl、K、Ca、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、As、Br、Mo 、Cd、Sb、Sn、Tl 和 Pb。 根据元素、使用的校准材料和使用的仪器，可以确定大约 0.0001 % 到 100 % 之间的浓度水平。 注 X 射线荧光光谱法可用作元素和杂质定性概览的快速方法，经过适当的校准后，它对于测定主要元素甚至微量元素（汞除外）非常有用，以便快速识别浓度增加的微量元素。 固体回收燃料 (SRF) 中的元素，例如在 SRF 生产过程中。 [外文原描述]： This document specifies the procedure for a determination of major and minor element concentrations in solid recovered fuel material by energy-dispersive X-ray fluorescence (EDXRF) spectrometry or wavelength-dispersive X-ray fluorescence (WDXRF) spectrometry using a calibration with solid recovered fuel reference materials or solid recovered fuel samples with known content. A semiquantitative determination can be carried out using matrix independent standards. This document is applicable to the following elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Mo, Cd, Sb, Sn, Tl and Pb. Concentration levels between approximately 0,000 1 % and 100 % can be determined depending on the element, the calibration materials used and the instrument used. NOTE X-ray fluorescence spectrometry can be used as a fast method for a qualitative overview of elements and impurities and after suitable calibration it is very useful for determining major elements or even minor elements (except Hg) in order to quickly identify increased concentrations of minor elements in solid recovered fuels (SRF), for example during SRF-production.
