Abstract

The application of ICP-AES method was investigated for the rapid analysis of impurities in titanium and it's alloy. Elements for analysis were Mn, Cu, Ni, Cr, Mo, Sn, Zr, Fe, Y, Al and V. Good results were obtained by using titanium as an internal standard, which were enough preferable to the precision and the accuracy in the comparison with chemical analysis.
After the acid decomposition of metal sample (0.5 g) and fuming of H2SO4, the solution is diluted to 100 ml with water for the ICP determination.
The detection limits in the present method are 0.0001% for Mn and Y, 0.001% for Cu, Ni, Cr, Mo, Zr, Fe and Al, and 0.01% for Sn and V, which mostly show better results than those of widely used analysis. In the determination of Ti-6Al-4V alloy, however, corrections are needed according to the contents of V and Al.
