| Abstract: | A method for fast determination of silicon content in gasoline by HF-XRF was developed. The precision of this method was inspected. The results showed that the linear correlation coefficient was more than 0.999 9 when the mass fraction of the silicon was 0-100 μg/g. The detection limit was 1μg/g for silicon，the standard addition recovery was in the range of 95.7%-103.0%，and the relative standard deviation was less than 5.79%. The results showed that this method is suitable for determination of silicon in gasoline. |
