Abstract

Tungsten and hafnium in tantalum alloys was determined by ICP-AES.The tungsten and hafnium were analyzed by multi-elemental spectral lines average method and corrected by the matrix matching and background correction methods.The recoveries for the elements are in the range of 98.0%—102.2%,and relative standard deviations are less than 1.50%.The method is rapid,simple with high accuracy.It was applied to product analysis with satisfactory results.
