The transfer mechanism of reactive oxygen and nitrogen species (RONS) at plasma-liquid interface involves extremely complex physical and chemical processes, which has numberous aspects remain unclear, making RONS transfer control a issue urge to be solved. In this study, An experimental system, in which the plasma irradiation area is strictly controlled while liquid column flow stability is maintained through improvements to the equipment, was constructed. Here, the OH radical transfer characteristics under plasma irradiation were evaluated. In this presentation, the decay properties of liquid-phase OH radicals and gas-liquid transfer characteristics will be reported.
