差分吸收光谱法(DOAS)与紫外荧光法自动测量空气中SO_2的对比

The Contrast Research for Auto Monitoring SO_2 between Differential Optical Absorption Spectroscopy (DOAS) and U.V. Fluorescence

DOAS自动监测系统越来越广泛用于环境空气质量监测中SO2、NO2的监测,将差分吸收光谱法与紫外荧光法自动测量空气中SO2进行对比实验,并对监测结果进行讨论和统计检验,得出两种方法测定空气中的SO2,其监测结果具有较好的相关性、一致性、两者无显著性差异,在今后的监测工作中可用DOAS自动监测系统代替传统的干法点式自动监测系统监测SO2,以降低运行成本,减少仪器维护量,节约经费。

DOAS auto monitoring system have been extensively using monitoring SO_2、NO_2 , By comparing Differential Optical Absorption Spectroscopy (DOAS) and U.V. Fluorescence and analyzing the statistical results, we get the conclusion that the two methods have good correlation and identification, and they don't have obvious difference. In the future, in order to reduce the cost we may use DOAS system instead of point type system.
