In this study, the simple and rapid quantification of Cr, As, and Se in bituminous coal was achieved by energy dispersive X-ray fluorescence (EDXRF) spectrometry using pressed and powdered samples. The accuracy of the EDXRF method was improved by spectral processing optimization so the net intensity of the analytical X-ray line reflected the actual value. The EDXRF method provides results that are comparable to those obtained using traditional chemical analysis methods with two types of samples and it reduces the analysis time by 66% for pellet samples and 90% for powder samples.

使用台式能量色散 X 射线荧光分析仪对烟煤样品中的铬、砷和硒进行简单快速的定量

在本研究中，通过能量色散 X 射线荧光 (EDXRF) 光谱法使用压制和粉末样品实现了烟煤中 Cr、As 和 Se 的简单快速定量。通过光谱处理优化提高了 EDXRF 方法的准确性，因此分析 X 射线线的净强度反映了实际值。EDXRF 方法提供的结果与使用两种类型样品的传统化学分析方法获得的结果相当，并且将颗粒样品的分析时间缩短了 66%，将粉末样品的分析时间缩短了 90%。
