Background, Purpose, and Project Achievements

Recently, fine bubbles (FB) have found applications in various fields. We have reported the effectiveness of water containing FBs (FB water) of approximately 100 nm diameter for removal of radioactive cesium from soil and gravel conglomerate and nonwoven cotton. In Fukushima, this method of radioactive contamination removal using FB water is currently under trial. We also investigated the FB water for its ability to retain freshness and for its coloring effect on cut flowers such as a gentian. The detailed mechanism underlying the performance of FB in the above-mentioned application is yet not well understood, although the relevance of ions (proton (H+) and hydroxide (OH-) ion) in solution has already been discussed by many researchers. Therefore, we are investigating the mechanism underlying the performance of FB water through electrochemical measurements.

Future Prospects

We reported the basic properties of fine bubble in water, and we also keep studying application research cooperating with many colleagues in industry, government and academia. So we will continue to research interdisciplinary study.
