Outline of Final Research Achievements

On the reaction of solid and gas in aqueous solution, we discussed the ultra-fine bubble(UFB) utilization and investigated a new electrochemical production method of UFB. As a result, it was speculated that the reaction rate of oxygen in the aqueous solution was determined by the amount of dissolved oxygen rather than UFB. Regarding the formation of UFB, the number of UFBs is not clearly changed in electrolysis alone, but in addition to electrolysis, there is a tendency of increase of the number of UFBs when giving longitudinal oscillation to electrodes. It is needed to further improve the analysis method of the number of UFBs.
