The properties of water surface discharge plasma for variety of pulse repetition rates are investigated.A magnetic pulse compression (MPC) pulsed power modulator able to deliver pulse repetition rates up to 1000 Hz, with 0.5 J per pulse energy output at 25 kV,was used as the pulsed power source.Positive pulse with a point-to-plane electrode configuration was used for the experiments.Experimental results show that the physical and chemical properties of water surface discharge are not influenced by pulse repetition rate, very different from those observed for under water discharge.The production yield of H2O2 and degradation rate per pulse of the orange II organic dye did not significantly vary at different pulse repetition rates under a constant discharge mode on water surface.In addition,the solution temperature, pH, and conductivity for both water surface and underwater discharge reactors were measured to compare their plasma properties for different pulse repetition rates.
