Simultaneous Determination of Major and Minor Components in Vanadium Slag by Wavelength Dispersive X-ray Fluorescence Spectrometry

A method for simultaneous determination of major and minor components in vanadium slag samples was provided by using lithium metaborate-lithium tetraborate fusion sample and wavelength dispersive X-ray fluorescence spectrometry.The factors affecting the determination such as flux, pre-oxidation, fusion temperature and release agent were studied in details in this paper. The matrix effect is corrected by the theoretical alpha coefficients. This method has been applied to the standard materials with a RSD of 0.1%-7.5%, and the determination results were consistent with the results obtained by other methods. Compared with classical chemical methods, this method has the advantages of higher accuracy, precision, and more efficiency.
