1.前言随着公害问题日益严重,对有害气体的测定必要性就不断增加起来。而且,测定的对象也不限于大气污染的场合,扩展到公害发生源(气体排出口),事业场内,汽车排气口等地方,必须测量的气体的种类也一直在增加着。本文专门想就经常可能发生公害的数种气体,分别说明它们的测定方法。最近,由于原子吸光和气相色谱等分析仪器的普遍应用,所以把使用这些仪器的方法也尽可能收入进来,从而就不只限于有害气体,譬如重金属类的分析方法也作了记载。
1. Introduction With the worsening pollution problem, the necessity of measuring harmful gases is constantly increasing. In addition, the target of measurement is not limited to atmospheric pollution. It extends to places where pollution occurs (gas outlets), business sites, car exhaust outlets, etc., and the type of gas that must be measured has also been increasing. This article is intended to explain how to measure each of several types of gases that are most likely to cause pollution. Recently, due to the widespread use of analytical instruments such as atomic absorption spectrometry and gas chromatography, methods for using these instruments have also been rewarded as far as possible so that it is not limited to harmful gases such as heavy metals.
