| Outline of Final Research Achievements |
By the ball-lightning discharge, first announced in 2002, decomposition performances and its abilities generating chemical active species, such as ozon and OH radicals, depending on the discharge polarities were studied experimentally.
As a result, its performance was evaluated by decomposition of indigo carmine dye and acetic acid,which are widely used for evaluation of water treatment. And it can be estimated about 1/2 of the maximum efficiency obtained by other water treatment, as initial results. We also found a difference between the decomposition characteristics due to the polarity of discharge and its active species. Furthermore, the decomposition process was examined by two-dimensional measurement of luminescence from active species and liquid chromatography analysis.
