Abstract
We tested deodorant capability of alkaline (pH11.2) and acidic (pH2.5, av.Cl2 40ppm) electrolyzed waters. Vaporized 12 compounds known as malodorant substances were sprayed with electrolyzed waters in a mixing chamber. Difference in the concentrations of the vapors before and after the treatment was measured to estimate the deodorant capability. As results acidic electrolyzed water showed high deodorant capability to ammonia, trimethylamine, pyridine, propionic acid, butyric acid and valeric acid, whereas alkaline electrolyzed water showed a specific deodorant capability to hydrogen sulfide. Methyl mercaptane, acetaldehyde, ethyl acetate, and methyl isobutyl ketone were resistant to the deodorant capability of both waters.
