The effects of various factors on the NO removal activity in the (NH4)2SO3 solution were investigated to explore more details and characteristics of the related reactions using full infrared sensor flue gas analyzer (FISFGA). It was found that the conversion yield of NO (9.0%.29.0%) was obviously improved with the increase of gas.liquid contact area, NO residence time and (NH4)2SO3 concentration as well as the adding of CuSO4. However, it was mainly limited by gas.liquid mass transfer rate and slightly inhibited by the gas velocity. Moreover, the FISFGA analysis revealed that two nitric oxide (NO) conversion route with different reduction product of N2O and N2 existed simultaneously upon the existence form of SO3 2-. It was confirmed by the calculations and the experiments of pH factor that the NO reduction steps were based on the following equation: (1) NO + HSO3- ⇋ N2O + SO4 2- + H+; (2) NO + SO3 2- ⇋ N2 + SO4 2-. In this system, Eq. (1) with N2O product was the major pathway, but the ratio of Eqs. (2) to (1) was intensified in the presence of CuSO4. It is believed that the suitable additives could promote the NO reduction to N2 furtherly.
