Abstract

The removal of NO by using Fe³⁺-H₂O₂ mixed reagent solution with the addition of EDTA was investigated in a lab-scale bubbling reactor. The effects of pH value, H₂O₂ concentration, NO inlet concentration and reaction temperature were assessed. The experimental results indicated that addition of EDTA into Fe³⁺-H₂O₂ mixed reagent solution can improve NO removal efficiency under weakly acidic conditions. When NO concentration exceeded 600 ppm, the gas-liquid reaction between NO and absorption liquid was controlled by liquid-film. The removal efficiency of NO increased with increasing reaction temperature.
