Unveiling the Impact of Operating Current on Active Species Generation in Pin‐To‐Water Plasma Activated Water System

Year: 2024

Type: article

Abstract: ABSTRACT This study explores plasma‐activated water (PAW) generation in a pin‐to‐water (P2W) setup, examining how operating current affects gas production and its interaction with neutral pH range water. High‐current mode (HCM‐32.3 mA) significantly increases hydrogen peroxide ( by 2x and nitrite () by 1.5x over low‐current mode (LCM‐19.5 mA), with and concentrations reaching 161 mg/L and 1070 mg/L, respectively. These findings align with increased gas production. The study underscores the air–water interface's role in PAW chemistry, with ICCD emission and chemical‐workbench (CWB) simulations providing further reaction insights. Overall, it highlights operating current as a critical factor in PAW chemistry and the role of in reactive nitrogen species formation.
