引言气态氢化物分离由于过程简单、方法灵敏、干扰较小,现已在原子吸收分析中广泛使用。然而原子吸收一般每次只测一个元素,分析速度受到了限制。加藤研作等和黄衍初等曾考虑用X射线荧光光谱(XRF)取代原子吸收,但他们提出的方法每次也只测一个元素,与原子吸收相比,缺乏竞争力。本文考虑到XRF的特点,通过选择适当的实验 Introduction The separation of gaseous hydride has been widely used in atomic absorption spectrometry because of its simple process, sensitive method and small interference. However, the atomic absorption is usually measured only one element, the analysis speed is limited. Kato et al., And Huang et al. (1990) considered the use of X-ray fluorescence (XRF) instead of atomic absorption. However, their proposed method only measures one element at a time and is less competitive than atomic absorption. This article takes into account the characteristics of XRF by selecting the appropriate experiment
