| Abstract: | This article reviewed several ferrous chelators used in removal of NOx and SO2 in coal-fired flue gas,including ferrous ammonium carboxyl chelating agents(FeⅡEDTA,FeⅡNTA) and ferrous sulfhydyl chelating agents(FeⅡ(CyS)2,FeⅡ(DMPS)2).The reaction mechanism of desulfurization and denitrification was indicated,and the advantages and disadvantages of different methods were discussed,which we would like to put forward proposals on development trend. |
