In this paper, the emission spectra of OH radical (A2Σ+→X2Π, 0-0) were successfully measured by optical emission spectroscopy (OES) in multi-needle to plate negative DC corona discharge at atmospheric pressure in humid ambient air. The influences of discharge power, distance between needlepoint and plate, and relative humidity on production and productive rate of OH radical have been investigated. The optimized parameters of excited OH radical under present experimental conditions were obtained from the analysis of experimental results.
► The optimized parameters of excited OH radical are obtained by OES.
► The discharge power of one needle is about 3 w.
► The distance between multi-needlepoint and plate is approximately 25 mm
► The range of relative humidity under normal temperature is from 40% to 60%.
