제목 NaClO2를 이용한 SO2·NOx 동시제거반응에서 반응용액 중의 이온농도와 배가스 중의 이차오염물 특성
초록 The simultaneous removal of SO2 and NOx was investigated using NaClO2 in the lab-scale bubbling reactor. The ion concentration of reaction solution and secondary pollutants were measured using auto-titrator and gas analyzers. To examine the reactivity of the oxidative reactant NaClO2, reactions were carried out at fixed temperature (T=35℃), pH 3.5, NaClO2 concentartion of 2 mol/L and input concentration of SO2 and NO 1800 ppm & 350 ppm respectively. Unreacted ClO2 gas which is secondary pollutant was absorbed into buffered KI solution for quantitative analysis. Concentration of NO3- ions in the reaction solution and ClO2 collected in absorber were analyzed quantitatively to study the utilization of sodium chlorite. The removal efficiency of SO2 and NOx were found about 90-98% and 70-81% respectively.
