The Chemical Properties of Air-water Discharge Induced by Double Dielectric Barrier Discharge

ABSTRACT

A set of air-water discharge induced by double DBD device has been designed to obtain hydrogen peroxide (H₂O₂) and ozone (O₃) levels, simultaneously. How the H₂O₂ and O₃ are being produced, which have extensively been studied by different experimental approaches such as air cooling, atomization amount, voltage applied, pH value and electrical conductivity (EC). The experimental results show that with the increase of atomization amount, O₃ output reduced slightly, while in the start H₂O₂ output increased that later decreased. On applying high voltages, O₃ output raised from 26kV to 32kV, which later decreased from 32kV to 34kV, in addition a constant increase trend seen in H₂O₂ output under like voltage conditions. EC also induced a gradual ascend in H₂O₂ output , while descends O₃ output in first instance at EC level 0 to 2500µs but later remained stationary at higher EC levels (2500 to 10000µs). Like many other factors, similar pattern seen while studying pH effects which initially boost and later decrease in the H₂O₂ output but two inflection points for O₃ output. It is concluded for the results that, H₂O₂ and O₃ output can reasonably be controlled under different physico- chemical conditions, hence to attain the desired results with potential usage in chemical pollution, material handling, biomedicine and lot more etc.
