“…7D). Fujita et al [46] reported that ozone adsorption capacity is strongly dependent on the amount of SiO 2 and the pore structure of the catalyst surface. The increased SiO 2 ratio is beneficial to the adsorption of ozone in aqueous solutions, and the adsorbed ozone was desorbed almost reversibly.…”

“…However, slowness of oxidation for some refractory pollutants and harmful by-products are serious problems in the conventional ozonation. Aiming at the simultaneous solution of these problems, a novel ozonation has been proposed through the use of ozone adsorbent (Fujita et al, 2004a). At the first step of our research, we found ZSM-5s adsorb a large amount of ozone from aqueous phase and its adsorption-desorption process was almost reversible.…”

This paper deals with a novel adsorbed phase ozonation process that enhances the reaction rate between ozone and organic pollutants, especially focusing on their reaction kinetics on ZSM-5s. In this study, we elucidated that adsorptive concentrations in ozone and organic chemical were dominant factors for the increases in reaction rate, and developed a novel method for predicting the reaction rates between ozone and organic chemical on ZSM-5s.
