Abstract

PURPOSE: In the denitration process using a NOx removing treatment solution containing Fe ions and one or more of SO3, HSO3 and polyamino carbonic acid, the ferric complex salt produced during the treatment is practically regenerated to ferrous salt to maintain the NOx removal rate of said treating soltuion for a long period of time.
