冷原子吸收法间接测定车间空气中的硫化氢

Indirect Determining Hydrogen Sulphide in Air by Cold Atomic Absorption Spectrometry

车间空气中硫化氢浓度的监测,是作为评价空气污染的重要指标之一,目前在职业接触限值配套检测方法中仍采用硫化氢的硝酸银目视比色方法,该法灵敏度较低,采集样品量大。本文提出了冷原子吸收法间接测定车间空气中的硫化氢含量,操作简便快速,结果准确,完全能满足车间空气中硫化氢含量测定。

In this article, Hydrogen sulphide has been analysed in the air by cold Atomic Absorption spectrometry.The fast speed and simplicity makes it possible for this method to be use in determining hydrogen sulphidein the air of workshop.
