Fe(II)EDTA in an anammox process to eliminate NO from flue gases.
NH4+ was eliminated through Fe(II)EDTA–NO reduction via anammox.
Fe(II)EDTA–NO-dependent anammox process produces less nitrate than conventional does.
Removal of complex NO and NH4+ exhibited high relativity.
Anammox is promising to remove nitrogen from wastewater and flue gases.
