空气中臭氧污染监测方法与应用

Methods and Applications of Ozone Pollution Supervision for Atmosphere

臭氧有消毒等作用,但在空气中浓度过大时也将造成环境污染。对红外吸收光谱法和气相滴定法在臭氧浓度监测中的基本原理进行了论述,并以红外吸收光谱法为例开展了臭氧浓度监测的应用。研究表明:臭氧污染与日常生产与生活规律密切相关,且与氮氧化物和一氧化碳等前体物浓度相比呈现一定的滞后性;相关部门应开展气相滴定法等前沿课题的研究,加强监测,积极做好空气中臭氧污染的防治工作。

Ozone has features including disinfection.At the same time,if its concentration in the air is too large,it will also cause environmental pollution.Basic principles of infrared absorption spectroscopy and gas phase titration in the supervision of ozone concentration are discussed.Research shows that,rules of ozone pollution and daily life and production are closely related,and have a certain lag effect compared with precursors concentrations including nitrogen oxides and carbon monoxide;the relevant research centers should carry out research on cutting-edge topics including gas phase titration to strengthen the supervision of ozone,and actively carry out the control work for the air pollution prevention.
