摘要: | The present study applying a plasma jet to activate water in a controllable environment is aimed to investigate the effect of a combination of (working/chamber gas) on the properties of plasma-activated water. After 10 min of activation, results reveal that a significant decrease in solution pH is observed with the presence of N-2. Hydrogen peroxide appears to be the major species for most gas mixtures, except [Ar + air/Ar] and [Ar + air/air], where nitrite and nitrate dominate. A gas mixture of [Ar + air/Ar] produces the maximum concentration of NO2-, while the maximum NO3- and H2O2 are observed for [Ar + air/air] and (Ar/Ar), respectively. Overall, the antibacterial efficacy correlates well with NO2- concentration. |
