Application of metal complexes absorption in wet NOx absorption system
金属络合吸收剂在湿法脱硝中的应用

Complexes absorption of NO is an important orientation in desulfurization and NO removal field.Starting from the metal complexes solution structures,this paper analysizes the ligand chemistry of metal centers such as iron and cobalt and binding of aminocarboxylate and thiochelate complexes.The kinetic data under different temperatures and pH are offered.The existing regeneration methods such as biotreatment,reductant reduction and electrochemical process were summized.The oxygen-insensitive solutions together with the waste product recycle are our long-term directions.
