Abstract
An atmospheric-pressure argon plasma jet was directly irradiated onto distilled water. Upon plasma jet irradiation, hydrogen peroxide (H2O2) was generated in the distilled water, and the H2O2 concentration increased with the duration of plasma jet irradiation. These results were obtained by semiquantitative determination using H2O2 test strips and by flow injection analysis (FIA). It is considered that, upon plasma jet irradiation, hydroxyl (OH) radicals are generated when high-energy electrons in a plasma jet collide with water (H2O) molecules in distilled water and bind to each other to form H2O2.
