Study on Detection of Environmental Air Pollution by Differential Optical Absorption Spectrometry

Abstract:

High quality air environment is needed for human health. Indoor air pollution comes from surface decoration materials and outdoor smoke pollution. In this paper, based on Differential Optical Absorption Spectrometry (DOAS), absorption spectra of main pollution gases HCHO, SO₂, NO, NO₂ are measured and their differential absorption cross sections are calculated. For ppm range of pollutant concentration, minimum measurement error of 9% is achieved by our experiments. It is sensitive for air pollution detection.
