Determination of Major and Minor Components in Coal Ash Samples by X-ray Fluorescence Spectrometry with Fused Bead Sample Preparation

A method for determination of SiO2, Al2O3, Fe2O3, MgO, CaO, Na2O, K2O, TiO2, MnO2, P2O5and SO3in coal ash samples by Axios X-ray fluorescence spectrometer with fused bead sample preparation was developed. The factors affecting analysis results including ratio of sample to flux, fusion temperature and preparation of standards were discussed. The matrix effect was corrected using fundamental parameter correction method. The method has been applied to the determination of these elements in National Standard Reference coal samples and the results are in agreement with certified values with precision (RSD, n=10) of less than 3%.
