| Outline of Final Research Achievements |
In order to generate OH radicals in atmospheric pressure discharge-induced plasmas, we have developed a new reactor which can be operated using a running water film by dielectric barrier discharge (DBD). The OH radicals in liquid were measured by the chemical probe method. It was found that the OH radical generation rate and energy efficiency in the water film type DBD was higher compared to the other discharge types.
Moreover, we have introduced 3D printing technology for the first time to the fabrication of non-thermal plasma reactors and verified the 3D printing technology could be used for the optimization of the non-thermal plasma reactor. In the experiment of decolorization of the dye solution, the performance using the developed reactor was superior to any other reactors. Finally we have developed a system which can be treated a 100 L liquid by the combination plasmas with filtration, and ozonation.
