摘要：
NO absorption and oxidation by K2S2O8 + Fe(II)EDTA system was studied in a lab-scale bubble reactor. The effects of different additives, reaction temperatures, pH values, K2S2O8 and Fe(II)EDTA concentrations on NO conversion were systematic investigated. Results indicated that NO conversion rate of K2S2O8 + Fe (II)EDTA system increased to 91.6% when concentrations of K2S2O8 and Fe(II)EDTA were both 30 mmol/L at 80 degrees C. NO conversion rate was positively correlated with the SO42- concentration in absorption solution, and it kept around 80% in a wide pH range, which made this technology to be a promising method for the denitrification of coal-fired flue gas.
