Abstract

We examined the effect of H2O2 on the removal of NO and NO2 by treatment with a Mg-Al oxide slurry. The removal of NO2 and dissolution of NOx species in an aqueous solution increased with increasing concentrations of H2O2. NO2 was reduced to NO2- by HOO- derived from H2O2. The contribution of Mg-Al oxide decreased with increasing H2O2 concentration. The addition of H2O2 to the Mg-Al oxide slurry promoted the removal of NO owing to the oxidation of NO to NO3- by H2O2. However, the contribution of Mg-Al oxide decreased with increasing H2O2 concentration.
