Studies of uranium—cerium admixture solutions by EDXRF spectroscopy

摘要: Uranium and cerium were studied in nitric acid solutions after presentation to an energy-dispersive x-ray fluorescence (EDXRF) spectrometer on filter-paper fixed Scotch tape. Ce Lα U peaks used as analyte lines excitation with a tungsten tube target at low potential (20 kV). These non-conventional conditions considered be suitable for contents of strongly but high uranium weakly nuclear fuel. Lower net integrated line intensities observed actinide compared lanthanide are discussed along the scattered, Auger Coster–Kronig responsible production back-ground before calibrations known concentrations. Difficulties establishing explicit relationship between these change matrix composition discussed. The concentrations mixed when results from various computer programs using regression analysis showed that algorithm developed by Plesch Thiele Siemens is better than others. An accuracy <2% was achieved. importance certified, standard or simulated reference materials realized quality occasional samples.
