| Outline of Final Research Achievements |
For the development of the advanced oxidation process (AOP) using zeolite compounds as solid catalysts, the evolution of active oxygen species by the catalytic decomposition of aqueous ozone was identified using the ESR-spin trapping method. It was confirmed that the hydrophilic zeolite was an effective catalyst for converting aqueous ozone into active oxygen species like hydroxyl radical or atomic oxygen. When applying the AOP using zeolite compounds as solid catalysts for the decomposition of humic acid, decolorization proceeded quickly, and the catalytic effect was clearly observed. However, complete decomposition, namely mineralization, was found to be sluggish, and the catalytic effect was much smaller than for the decolorization. It was confirmed that carboxylic acids formed through the decomposition of organic compound were the radical scavenger.
