Paper Abstract

An ultra-low emission Cl2 monitoring optical system based on differential optical absorption spectroscopy has been set up. We have found through comparison experiments that UV reflection enhanced aluminum is damaged and the dielectric film mirror is intact under high concentration of Cl2. Then verify the performance characteristics of ultralow Cl2 emission online monitoring device. The maximum absorbance of 50ppm Cl2 exceeds 0.1, while the 30ppm Cl2 reaches 0.063, so the measurement range can be 0-95 mg/m3, which meets the maximum allowable emission concentration of Cl2 required by the new regulations for detection of 65mg/m3.
