    • Abstract
  • A method for the determination of tungsten contents in Ta-2.5 W and Ta-10 W was established by using the emission spectrometer. The work curve was made by pure tungsten standard solution of high purity tantalum hydroxide matrix, the analytical line of tungsten was 209.475 nm, the linear range of the method was 1.25%~15.00%, the recovery rate was 93.0%~99.0%, and the relative standard deviation (n=11) of the measured values was less than 0.8%.
