In order to eliminate the matrix effect occurred in preparing samples by tabletting method based on the means of X-ray fluorescence spectrum, the calibration curves are plotted by using internally piloting standard samples prepared by blending the slag samples resulted from the actual production with pure substances. The laboratory tests show that the uniformity of samples prepared by drum blending method is equivalent to that of national standard substances and the content in prepared samples is the same as the results tested by chemical method. Based on that the series of calibration samples such as Al2O3, CaO and MgO can be prepared flexibly according to the actual situation of preparing samples and therefore the matrix effect is eliminated while the accuracy for analyzing the slag samples by sample-preparing method based on X-ray fluorescence spectrum tabletting is improved.
