Outline of Final Research Achievements

An evaluation of the presence of micro/nano bubbles using radicals generated in the decay phenomenon of bubbles by ultrasonic waves was carried out, and the following findings were obtained. ① From the examination of the disappearance of micro/nano bubbles by ultrasonic wave, the transition to the destruction occurs rather than the generation of the bubble in high frequency. ② The number of micro/nano bubbles can be estimated from the amount of radicals generated. ③ It is possible to estimate the number of micro/nano bubbles from the amount of organic matter decomposed by radicals generated in the decay of micro/nano bubbles.
