摘要：
The study on the removal of NOfrom simulated flue gas has been carried out in a lab-scale bubbling reactor using acidic solutions of sodium chlorite. Experiments were performed at various pH values and inlet NO concentrations in the absence or presence of SOgas at 45℃. The effect of SOon NO oxidation and NOabsorption was critically examined. The oxidative ability of sodium chlorite was investigated at different pH values and it was found to be a better oxidant at a pH less than 4. In acidic medium, sodium chlorite decomposed into ClOgas, which is believed to participate in NO oxidation as well as in NOabsorption. A plausible NOremoval mechanism using acidic sodium chlorite solution has been postulated. A maximum NOremoval efficiency of about 81% has been achieved.
