The experiment was performed for in order to remove NOx which is generated in the Ship's engine. it was performed test in order to remove NOx which is generated in the Ship's engine. It was used as the oxidizing agent sodium chlorite. Use the oxidizer is nitrogen monoxide was oxidized to nitrogen dioxide. and was tested pH adjustment to increase the efficiency of oxidizing. An aqueous solution of sodium hydroxide was used for the nitrogen dioxide absorbent. Low concentration of the solution, it showed a high efficiency. improves the absorption efficiency by add additives.
