Abstract

Surface dielectric barrier discharge (SDBD) ignited directly from the liquid electrodes at the 3-phase gas/liquid/solid interface represents a novel approach in both water and polymer surface treatment methods. This study investigates the gaseous and liquid-phase reactive oxygen and nitrogen species (RONS) generated by this discharge. The impact of the discharge power and treatment duration on the concentration of these species in both gas and liquid is explored. The spatial development of ozone, the prevailing molecule produced by air dielectric barrier discharge, is studied. The production yields of plasma-generated species in the gas are described. Additionally, the electrical measurements of the SBDB with liquid electrode are presented and its characteristics are discussed. The combined investigation of RONS production yields, electrical discharge characterization, and in-situ ozone evolution provides important information regarding the presence of the reactive species in the vicinity of the plasma discharge, supporting further development and targeted applications of this technology.
