摘要
本文介绍一种用N_2O-C_2H_2火焰原子吸收法测定NT-P100HT高温合金中痕量钙的简便准确快速的方法。在所选条件下,特征浓度为0.015μg/ml1％.检测限为0.0042μg/ml,相对标准偏差小于10％。
This paper describes a simple,rapid and accurate method for determination of trace calcium in NT-P100HT high temperature alloy by N_2O-C_2H_2 flame atomic absorption spectroscopy.The characteristic concentration is 0.015μg/ml 1%.The detection limit is 0.0042/μg/ml.The relative standard deviation is less than 10%.
