| Abstract: |
| In this paper, the detection techniques of nitrogen dioxide in the air in recent years are summarized, which are divided into two categories according to the detection principles:indirect detection technique and direct detection technique. Indirect detection techniques include spectrophotometry, ion chromatography, sensor method, fluorescence spectrometry and chemiluminescence. Direct detection techniques include differential optical absorption spectroscopy, laser induced fluorescence and cavity ring-down spectroscopy. The basic principle, research status, advantages and disadvantages of each detection technology are introduced, and the development prospect of the detection technique for nitrogen dioxide in air is prospected. |
