从本世纪三十年代起,由于工业生产所产生的氧化氮对空气污染日益加重,对人类健康和动植物已造成了不良影响,从而,引起了人们的关注。环境科学工作者在对氧化氮的毒性进行深入研究的同时,对其分析方法也进行了研究。至今,已有多种空气中氧化氮的测定方法,其中包括容量分析法、比色分析法、化学发光法、电化学分析法、色谱分析法及紫外、红外分析法等。现在常用 Since the 1930s, due to the increasing pollution of nitrogen oxides produced by industrial production, human health and animals and plants have been adversely affected. As a result, people have drawn their attention. Environmental science workers in-depth study of the toxicity of nitrogen oxides at the same time, its analysis has also been studied. So far, there have been a variety of methods for the determination of nitrogen oxides in air, including volumetric analysis, colorimetric analysis, chemiluminescence, electrochemical analysis, chromatographic analysis and UV and IR analysis.
