| Abstract: | The application of Air-Ethane flame atomic absorbing spectral method to measure the content of cuprum, iron, magnesium in electrochemistry impregnating solution of ethyl alcohol is studied. Introduces the optimum measuring conditions for Cuprum, iron, magnesium and density in which a fine liner range is presents . Makes a synthetic consideration to interference factors. The method has the advantages of high sensitivity. And this method is proved to be simple operation, easy master, short analyzing cycle, Less interference and good in selectivity and reappearance. The relative standard deviations are all less than 1.0% in ten sample measures, and the standard adding recovery is in the range of 97%-102% in six sample measures. |
