摘要
采用N2O-C2H2火焰原子吸收光谱法进行高温镍基合金中锡含量的测定。考察了锡的最佳测定条件以及线性范围的浓度。在样品测定中对干扰因素进行了综合考虑。该方法灵敏度高、选择性好,操作简便、容易掌握、分析周期短等优点。方法完全适用于高温镍基合金中锡含量的测定,结果令人满意。
The application of nitrous oxide-ethane flame atomic absorption spectrometry method to measure tin in the high temperature nickel base superalloy was studied.The optimum measuring conditions for tin and the linear concentration range were introduced. The method has the advantages of high sensitivity, less interference, high selectivity and good reproducibility. It is fully suited to measure tin in the high temperatue nickel base superalloy.
