Abstract Reaction pathways and specific mechanism of NO removal by non-thermal plasma (NTP) were for the first time investigated via FT-IR measurements. It was found that NO removal was attributed to a co-effect of N and O radicals but centered on the latter, and only O radical worked for NO oxidizing to NO2, since O3 can't be obtained under the lock of fast NOx reaction. O2 content regulated reaction behaviors that reduction pathways was dominating when O2 content was 30 °C) and the addition of flue gas components like H2O, CO and CO2 showed negative effects on NO removal, while HCl were on the contrary. SO2 revealed nearly no influence.
