| Abstract: | A method was developed for the determination of beryllium and calcium in brazing alloy of titanium matrix by ICP-AES. Spectral interferences and the effect of matrix on the determination were studied. The analytical lines of Be and Ca were selected. The instrument parameters on the determination were discussed and optimized. The recovery is in the range of 98 % to 102%, the relative standard deviation is less than 2% . The method was suitable for determining beryllium and calcium in brazing alloy of titanium matrix. |
