摘要：

In this work, a relationship between the role of NH3 and the properties of mineral oxides (alpha-Fe2O3, alpha-Al2O3, CaO, and MgO) in the evolution of NO3-, SO42-, and NH4+ has been established. It was found that the promotion effect of NH3 was more favorable for the formation of NO3- (or SO42-) and NH4+ on acidic alpha-Fe2O3 and alpha-Al2O3 due to acid base interactions between NO2 with NH3 or between SO2 and NH3, while this effect was weaker on basic CaO and MgO possibly due to their basic nature. The acid base interaction (NO2/SO2 with NH3) overpowered the redox reaction (SO2 with NO2) on F...
