Abstract:

In this paper, using a Hoffmann glass reactor as an electrolysis instrument, the mechanism of liquid phase reactions resulting from the application of a DC atmospheric pressure discharge was studied experimentally for argon, oxygen, and nitrogen gases in an aqueous solution, and the effects of electron and positive ion radiations on the liquid phase were investigated separately for plasma anodic and cathodic interfaces. Electrical conductivity (EC), total dissolved solids (TDS), the concentrations of hydrogen cations , hydroxide anions , and oxygen gas of water were calculated and compared in conventional electrolysis and plasma-liquid anodic and cathodic interfaces for short time t=6min in periods of ∆t=2min. The results show that plasma anodic and cathodic interfaces can be used as a new electrolysis method to change and control the properties of liquids. In addition, nitrogen and oxygen plasmas were observed as a factor in increasing reactions and more considerable changes in water properties than argon plasma. That was due to the presence of reactive species derived from oxygen and nitrogen feeder gases in addition to species of atmospheric gases and water vapor. Further, liquid cathode discharge was more effective than liquid anodic discharge at producing more reactive species and changing water properties.
