Abstract
Ferrous chelate absorption is deemed a promising method for NO removal from flue gas, but the key problem is the difficulty to regenerate the absorption solution, i.e. the complexes of FeII(EDTA)NO and FeIII(EDTA) in the solution. Two bacterial strains isolated recently from the sludge of the denitrification step of a municipal wastewater treatment plant could be applied effectively to regenerate the absorbent werePseudomonas sp. andklebsiella trevisan sp. Pseudomonas sp. exhibited high reduction ability on FeII(EDTA)NO and theklebsiella trevisan sp. was more suitable for FeIII(EDTA) reduction.
