Energy-dispersive X-ray fluorescence analysis with pyrographite crystals and small X-ray tubes
Journal of radioanalytical chemistry(1980)
摘要
The advantages and peculiarities are described of energy-dispersive X-ray fluorescence analysis with preliminary energy selection of the radiation coming from a sample with the help of a cylindrical system of pyrographite crystals. The results of application of this method to the analysis of U and transuranium elements in the solutions of spent nuclear fuel reprocessing are presented. Minimum detectable concentration of U for determination directly in a solution is 0.15 ppm.
