Abstract：Fe(Ⅱ)EDTA complex denitration technology is a commonly used method in flue gas denitration technology. However， Fe2＋ is easy to oxidize， the loss is large， and the secondary use is difficult， resulting in high operating costs. In order to achieve the purpose of reusing the complexing solution， this article used the palladium-foam nickel electrode to electrocatalyze the regeneration of the denitration complexing solution， and mainly explored the effect of catalyst loading， current density and reaction temperature on the electrocatalytic regeneration effect of palladium-foam nickel electrode. The experimental results show that when palladium was loaded on the nickel foam electrode by chemical replacement， the load was 1.0 mg·cm－2， the current density was 6 mA·cm－2， and the temperature was 30 ℃， the regeneration effect was the best， The conversion rate of Fe(Ⅱ)EDTA-NO was 90.0%， the selectivity of NH was 10.0%， the selectivity of N2 was 90.0%， and the NOx removal efficiency of the regeneration solution was greater than 80% within 25 min.
