Abstract
Silver as a metal catalyst has been used to remove odorous compounds. In this study, silver particles in nano sizes () were prepared on the surface of , the supporting material, using a sputtering method. The silver nano-particles were dispersed by dissolving into water, and the dispersed silver nano-particles in the aqueous phase was applied to remove inorganic odor compounds, and , in a scrubbing reactor. Since ammonia has high solubility, it was removed from the gas phase even by spraying water in the scrubber. However, the concentration of nitrate () ion increased only in the silver nano-particle solution, implying that the silver nano-particles oxidized ammonia. Hydrogen sulfide in the gas phase was rapidly removed by the silver nano-particles, and the concentration of sulfate () ion increased with time due to the oxidation reaction by silver. As a result, the silver nano-particles in the aqueous solution can be successfully applied to remove odorous compounds without adding additional energy sources and producing any harmful byproducts.
