Abstract

Abstract

In order to get extensive knowledge of radical production in a corona induced non-thermal plasma, the effect of discharge parameter, gas condition on emission intensity of OH(A2S+→X2P, 0-0) in a nozzle-to-plate corona radical shower system are experimentally investigated using emission spectroscopy considering the collisional quenching rate. The results are that: both discharge voltage and current have direct influence on OH emission, OH production increases as discharge power rises; remarkable emission spectrum of OH(A2S+→X2P, 0-0) is detected in N2 DC corona discharge, but few OH radicals exist in air discharge; humidification of electrode gas can enhance the OH emission, and the existence of Ar increases the OH emission, while O2 may reduce the OH emission, the possible reason is th
- oh radical,
- emission spectrum,
- corona,
- radical,
- discharge,
- quenching
