“…They found that the reaction under low concentration of NO was first-order with respect to NO and first-order with respect to KMnO 4 , which was the same as the case with high NO concentration done by Sada et al (1977). The rate of above reactions is regarded as the mth order relative to NO and the nth order relative to MnO4'.…”

Absorptions of NO by neutral and alkaline solutions of KMnO 4 were performed in this study to clarify the reaction kinetics. The experiments were mainly carried out under 50°C, which is the common operating temperature for wet scubbers.According to the assumption that the absorption of NO was developed under the fast pseudo-mth reaction regime, which is verified in the experiments, the absorption rate of NO into KMnO 4 solutions is found to be negative half-order dependent on P NO and first-order dependent on [KMnO 4 ]. The addition of NaOH into the solutions of KMnO 4 would 801 increase the absorption rate of NO. The absorption rate of NO at 25°C is lower than that of 50°C. In the ranges of this study, the absorption rate of NO would not change by changing the gas flow rate and O 2 concentration. NO 2 -is the dominate ion in the liquid phase for this study. However, the [NO 3 -]/[NO 2 -] ratio increases with the increasing NaOH concentration.

Wet removal of nitric oxide (NO) from simulated flue gas by an ultraviolet (UV)/H 2 O 2 advanced oxidation process was studied in a semi-continuous and small-scale UV-bubble column reactor. The effects of the H 2 O 2 concentration, UV radiation intensity, gas flow, and liquid layer height on NO removal efficiencies were studied. The results showed that an increase in the H 2 O 2 concentration, UV radiation intensity, or liquid layer height could enhance NO removal. The NO removal was inhibited by an increase of the gas flow. The ion products in solution were measured with ion chromatography, and a mass balance for the nitrogen element in NO from simulated flue gas was calculated. Potential effects of solution pH change and ion products in solution were also discussed.
