Condition optimization of X-ray fluorescence spectrometry with fusion sample preparation for determination of ten major and minor components in manganese ores

A fast and simple approach to directly determine sio2. Al2O3. Fe. Mgo. Cao. K2O. Mn. Tio2. P and Zn in manganese ores samples by X-ray fluorescence spectrometer(XRF) was developed. This method used a glass fuse piece technique with Li2 B4 O7. Libo2 and lif(Mass ratio:45:10:5) as the flux, NH4 NO3 as the oxidant, libr as the stripping agent. Several experimental parameters were optimized, and the analytical figures of merit were evaluated. The components in the certified reference material of GBW07261~GBW07266 were determined by the proposed method. The relative standard deviation(RSD, n = 12) was less than 2%. The accuracy test was conducted with synthetic samples. The results were consistent with the certified values
