Abstract— Cold Atmospheric Pressure Plasma Jets (CAPPJs) was generated by using column dielectric barrier discharge has been investigated. In this study, we evaluated the ability of plasma jet to decrease the pH in aqueous solutions. Plasma jet was generated by a sinusoidal AC high voltage at 12 kV and at frequency 26 kHz. Plasma activated medium (PAM) was produced by exposing aquadest water to the CAPPJs. The duration of exposing plasma jet was set at 5 minutes to 35 minutes, with an interval of 5 minutes. Plasma exposures were performed at the distance at 2 cm between plasma jet tube output and the upper surface of the liquid medium. On the results obtained in this experiment, the pH values at 2.7 in plasma-activated medium with exposure of plasma jet. We found that the pH of PAM decrease by a duration of exposure plasma jet. Cold Atmospheric Pressure Plasma Jets can significantly decrease the pH in aqueous solutions.
