1 INTRODUCTIONrnThe emission of nitrogen oxides (NOx) is one of the major causes of acid rain.The use of metal chelate additives in wet flue gas desulfurization (FGD) systems for combined removal of NOx and SO2 has attracted a great deal of attention[1,2]. FeⅡ(EDTA), (EDTA, ethylenediaminetetraacetate) is one of the most promising additives to promote the solubility of NO by formation of FeⅡ(EDTA)NO.
