Study on ozone oxidation of ammonium sulfite in aqueous solutions

摘要

This paper is focused on the situation that the by-product ammonium sulfite produced in the flue gas desulfurization of ammonia process, which carried ozone oxidation experiments. In the reaction container, studied the effect of the factors as oxidation reaction temperature, pH value, ozone flow and initial concentration on the reaction rate of ammonium sulfite oxidation. Then, conducted the oxidation kinetics experiment under the condition that only use ozone. The results showed that ammonium sulfite and ozone concentration are both simple first-order kinetics response in the condition that only the ozone oxidation reactions.
