A method for the determination of CaO, MgO, Al2O3, SiO2, P, MnO, TFe2O3 and S in dolomite by X-ray fluorescence spectrometry with fusion and pressed power pellet sample preparation was developed. The interferences from spectral overlap and matrix effect were corrected by experience alpha coefficient and internal standard with scattered radiation. The method has been applied to the determination of these components in national and provincial standard reference materials and the results are in good agreement with the certified values with precision of less than 10%RSD (n = 12).
