Review on the NO removal from flue gas by oxidation methods
2021, Journal of Environmental Sciences (China)Photocatalytic removal of NO and Hg<sup>0</sup> using microwave induced ultraviolet irradiating H<inf>2</inf>O/O<inf>2</inf> mixture
2020, Journal of Hazardous MaterialsCitation Excerpt :Then the effluent of this wet scrubber can mix with that from the MW-UV/H2O-O2 reactor. Subsequently, this mixed solution can be treated by using UV light to decompose the trace NO2− into N2 (Hao et al., 2019c; Carole et al., 1995). It was reported that the decomposition rate of NO2− would increase 4 times in the presence of UV, and the role of UV light in accelerating NO2- decomposition was also confirmed in our previous work (Hao et al., 2019c).
Cooperative removal of SO<inf>2</inf> and NO by using a method of UV-heat/H<inf>2</inf>O<inf>2</inf> oxidation combined with NH<inf>4</inf>OH-(NH<inf>4</inf>)<inf>2</inf>SO<inf>3</inf> dual-area absorption
2019, Chemical Engineering JournalCitation Excerpt :The final products were mainly (NH4)2SO4, NH4NO3 and NH4NO2. But due to the instability of NH4NO2 under the heat and the UV light [44], it was then decomposed as N2 and H2O (Eq. (21)) [34], or partly converted to NH4NO3 (Eq. (11)) [44]. Hence, after a period time, the main product was the mixture of (NH4)2SO4 and NH4NO3, moreover the concentration of (NH4)2SO4 was far higher than that of NH4NO3 according to the IC results.2HO + SO2 → 2H+ + SO42−H2O2 + NO → NO2 + H2O3H2O2 + 2NO → 2NO3− + 2H2O + 2H+H2O2 + SO2 → 2H+ + SO42−HO + NO2 → NO3− + H+H2O2 + 2NO2 → 2H+ + 2NO3−NH4+ + NO2− → N2 + 2H2O

2003, Chemical Engineering ScienceCitation Excerpt :In order to design remediation strategies, a thorough understanding of the kinetics and mechanism of this reaction along with the reaction rate parameters, namely pH, concentration of reactants, and temperature, is desired. Moreover, understanding the reaction mechanism between ammonium ion and nitrite ion will help elucidate the thermal decomposition of aqueous ammonium nitrite (NH4NO2), which is relevant to the observed nitrogen losses from aquatic environments and soils (Harrison, Malati, & Smetham, 1995). Consequently, the purpose of this work was to study the reaction using first principles.
