| Abstract: | The immobilization of liquid example is realized by the filter paper as carrier. By using the stand curve method on the X-ray fluorescence spectrometer, determination of conditions, sample preparation, calibration curve and data processing, the compositions of CaO, MgO, Fe2O3 and Al2O3 in the WPA are determined quantitatively. By this method, the sample preparation and analysis process are sample, quick, exact, and with the low cost, which can reach the request of chemical production. |
