Analysis of Cobalt and Nickel Bases Cathodes by X-Ray Fluorescence Spectroscopy

Abstract

In this work, Al, Cr, Cu, Fe, Ni, Si and Y were determined in SDP-6 cathodes based on cobalt and SDP-1 and AZh8 nickel-based cathodes by x-ray fluorescence spectroscopy. The calibration dependences are corrected taking into account the superposition of signals from interfering elements on the analytical signal and changes in intensity caused by inter-element influences in the matrix. A standard-free analysis was carried out using the method of fundamental parameters. The correctness of the results obtained was confirmed by a comparative analysis by atomic emission spectroscopy and high-resolution mass spectrometry with a glow discharge.
