A composite-liquid absorbent(CLA),NaClO/KMnO4,for simultaneous desulfurization and denitrification(SDD)was studied in a homemade bubbling reactor.The experimental results showed that the CLA configured by sodium hypochlorite(NaClO)and potassium permanganate(KMnO4)had a very good synergistic effect on SDD.The effects of NaClO concentration(CNa),KMnO4 concentration(CK),gas space velocity(Vg),initial p H value,and temperature of the absorption liquid(Ts)on efficiencies of the SDD were investigated.Under the optimal reaction conditions,the best removal efficiencies were 100%for sulfur dioxide(SO2)and above 94%for nitric oxide(NO).The ion chromatography and titration were used to analyze the changes of both the ion species and concentrations in the liquid before and after the reaction.According to the experiment results and related literature,the reaction mechanism of the SDD based on the CLA was proposed. 展开更多
