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

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.
