| Abstract: | The research on the analytical method for determining trace tungsten in RE metal had been done. Dissolving RE metal in acid solution,tungsten in RE metal was turned into tungsten trioxide,solving the difficult problem on disso lution of tungsten metal,Through the experiment about standard addition and standard deviation of tungsten, it was concluded that the accurate and precision of the analytical method used for determining trace tungsten in RE metal can meet the requirement on analytical quality of tungsten. |
