Abstract
본 연구에서는 전기분해 처리된 해수의 유효염소농도와 온도에 의한 배가스 중 NO의 산화 특성을 실험적으로 살펴보았다. 실험은 무격막식 전해수가 채워진 버블링 반응기에 반응가스를 공급하여 NO 농도의 변화를 분석하였다. 폐순환 전기분해 시스템의 경우 정전류 조건에서 전해 시간이 길어질수록 전해수 내에 유효염소농도가 상승하였고, 전해수의 유효염소농도가 높을수록 NO가 <TEX>$NO_2$</TEX>로 산화되는 반응이 촉진됨을 확인하였다. 또한 동일한 유효염소농도를 가지는 전해수의 경우에도 온도가 높을수록 NO 산화율이 증가하였다. In this study, we investigated NO oxidation characteristic that depends on available chlorine concentration and temperature of seawater which is treated by un-divided electrolysis. Reactant gas passed through bubbling reactors which is filled with electrolyzed water and then NO concentration change was analyzed. In the closed-loop electrolysis system, concentration of available chlorine increased with electrolysis time. The higher oxidation rate of NO to <TEX>$NO_2$</TEX> was obtained with the higher concentration of available chlorine. Oxidation of NO was fast when temperature of electrolyzed water was high, in the case of same concentration of available chlorine.
