本文件规定了通过能量色散X射线荧光光谱法(EDXRF)或波长色散X射线荧光法(WDXRF)测定固体回收燃料材料中主要和次要元素浓度的程序使用固体回收燃料标准物质或已知含量的固体回收燃料样品进行校准的光谱测定法。可使用矩阵独立标准进行半定量测定。 X射线荧光光谱法可作为元素和杂质定性概述的快速方法,经过适当校准后,它对于测定主要元素或甚至次要元素(汞除外)非常有用,以便快速识别固体回收燃料中次要元素浓度增加的情况(例如:。 G在SRF生产过程中)。 本文件适用于以下元素:钠、镁、铝、硅、磷、硫、氯、钾、钙、钛、钒、铬、锰、铁、钴、镍、铜、锌、砷、溴、钼、镉、锑、铊和铅。根据元素、使用的校准材料和使用的仪器,可以确定约0000 1%及以上的浓度。
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.
