吸收光谱分析法在氮氧化物检测的应用

Application of Absorption Spectrum Analysis in the Detection of Nitrogen Oxides

为提升对空气环境中污染物的测定结果的准确性,在对吸收光谱分析法测定气体浓度原理分析的基础上,分别分析了一氧化氮和二氧化氮气体的性质并结合吸收光谱分析法原理确定了浓度测定方法,并根据设计方案分别搭建了实验平台验证了吸收光谱分析法测量结果的最小测定值、测定精度等指标,并取得理想结果。

In order to improve the accuracy of the determination results of pollutants in the air environment,based on the analysis of the principle of gas concentration determination by absorption spectrum analysis,the properties of nitric oxide and nitrogen dioxide gas are analyzed respectively,and the concentration determination method is determined by combining the principle of absorption spectrum analysis.According to the design scheme,experimental platforms are built to verify the minimum measurement value and measurement accuracy of the measurement results of the absorption spectrum analysis method,and the ideal results were obtained.
