Abstract
The determination of Si, Y, Fe, Ni, Cu, Mg, Cr and Co in the cathodes of the VSDP-11 and VSDP-16 brands based on aluminum by the method of х-ray fluorescence spectroscopy was carried out. 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.
