氧化二氮-乙炔火焰是J.B.Wilis提出的一种高温火焰,它能使许多高温元素的金属氧化物原子化,从而使火焰原子吸收法可测的元素从三十几个扩展到七十几个。目前,氧化二氮-乙炔火焰原子吸收技术在国外已普遍使用,而国内运用较少。本文试验了用氧化二氮-乙炔火焰原子吸收法连续测定镍基高温合金中的钨、硅、钒、铝、钛的分析条件,确定了分析方法,获得了比较满意的结果。
Nitrous oxide - acetylene flame flame is JBWilis proposed a high temperature flame, which can make a number of high temperature elemental metal oxide atomization, making flame atomic absorption method measurable elements expanded from thirty to seventy . At present, nitrous oxide - acetylene flame atomic absorption technology has been widely used abroad, while less domestic use. In this paper, the conditions for the determination of tungsten, silicon, vanadium, aluminum and titanium in the nickel-base superalloy by continuous nitrous oxide-acetylene flame atomic absorption spectrometry were studied. The analytical methods were determined and satisfactory results were obtained.
