Abstract

Emission spectrum of the bipolar pulsed discharge in water-air mixture has been measured in the near-ultraviolet (UV) region using an Inspectrum 300 charge-coupled device (CCD) spectrograph. Effects of several parameters including peak-to-peak voltage, pulse repetitive frequency, etc., on the relative UV radiation intensity have been investigated. Experimental results show that bipolar pulsed discharge in water-air mixture emits strong UV radiation. The emission spectrum of the discharge has a wide range. The applied peak-to-peak voltage, pulse repetitive frequency, and air flow rate have positive effect on the relative intensity of the second positive band of nitrogen at 337.1 nm. However, solution conductivity has negative effect
