| Abstract: | The content of twenty-one elements such as Na etc. are determined by X-ray fluorescence spectrometry in the refly dust. The standard samples are artificially made. The calibration curve is calculated by the regression method. The matrix effect is corrected by using the scatter line internal standard method and the empirical coefficient method. This method gains good precision and accuracy, so the analytical results are satisfactory. |
