摘　　要：总结了近 2 0多年来液相络合法脱除烟气中NOx 的研究成果 ,详细叙述了亚铁氨羧和亚铁含—SH基二类螯合剂单独脱氮和同时脱硫脱氮的反应机理、动力学、吸收液的再生和过程的影响因素 ,指出了该工艺存在的主要问题 。The research results about removal NO x from flue gas with aqueous solution of ferrous chelates in last more than 20 years are reviewed in this paper. The reaction mechanism, kinetics, impact factors, and the regeneration of absorption solutions accompanying the processes of individual and simultaneous removal of NO x and SO 2 with ferrous aminopoly carboxylic chelate and ferrous thiochelate solutions are presented in detail. The main problems of the processes are pointed out, and the direction of the research for the process is proposed.
