Abstract
In this study, we investigated the characteristics of NO oxidation using un-divided electrolyzed seawater as oxidant. The concentration of available chlorine and the temperature of electrolyzed seawater are increased with electrolysis time in the closed-loop constant current electrolysis system. While NO gas flow through bubbling reactor which is filled with electrolyzed seawater, the oxidation rate of NO to $NO_2$ is increased with the concentration of available chlorine and the temperature. $NO_2$, generated by oxidation reaction, is dissolved in electrolyzed seawater and existed as $HNO_3{^-}$ ion.
