同步辐射讲座 第二讲同步辐射X射线荧光及其在植物微量元素分析中
The use of synchrotron radiation x-ray fluorescence inmicroelemental analysis in plants
-
摘要: 比较了同步辐射(SR)X射线荧光(XRF)、电子和质子激发的X射线谱，介绍了XRF谱的采集方法及数据处理方法(主要是能谱方法)、能谱方法的无标样(基本参数法)定量分析原理，以及近期在植物微量元素分析中得到的结果.Abstract: Synchrotron radiation (SR) X-ray fluorescence (XRF) and X-ray spectra excited by electron and proton beams are compared. The XRF data acquisition and processing, mainly by energy dispersion, are described. The principle of standardless quantitative analysis (basic parameter method) is explained. The SR-XRF trace analysis results obtained from several plants are shown.
