氢化物原子吸收法测定微量元素,近年来广泛应用,国内外已有不少报导。但多采用较复杂的氢化物发生系统,而且要惰性气体作载气,使野外地质工作中大量化探样品的及时分析受到限制。本文介绍一种自行设计的最简易氢化物发生器与常规空气——乙炔火焰原子吸收相结合测定微量锑的方法。在大量试验的基础上,本文对氢化物发生器的制造及应用,各种测试条件的选择和控制,干扰及其消除等作讨论。本法设备简单,造价低廉,操作方便,灵敏度较高,
Determination of trace elements by hydride generation atomic absorption spectrometry, widely used in recent years, there are many reports at home and abroad. However, more complex hydride generation systems are used, and inert gas is used as a carrier gas, which limits the timely analysis of a large number of geochemical exploration samples in field geology work. This paper presents a method for the determination of trace antimony by the simplest hydride generator designed by ourselves and the conventional air-acetylene flame atomic absorption. Based on a large number of experiments, this article discusses the manufacture and application of hydride generator, the selection and control of various test conditions, interference and elimination. This method is simple equipment, low cost, easy operation, high sensitivity,
