Abstract

A pulsed discharge, a DC corona discharge, and a plasma jet are separately generated above a water surface, and reactive oxygen species and reactive nitrogen species (ROS/RNS) in the water are investigated. ROS/RNS in water after the sparging of the off-gas of a packed-bed dielectric barrier discharge (PB-DBD) are also investigated. H₂O₂, NO₂ −, and NO₃ − are detected after plasma exposure and only NO₃ − after off-gas sparging. Short-lifetime species in plasma are found to play an important role in H₂O₂ and NO₂ − production and long-lifetime species in NO₃ − production. NO_x may inhibit H₂O₂ production through OH consumption to produce HNO₂ and HNO₃. O₃ does not contribute to ROS/RNS production. The pulsed plasma exposure is found to be effective for the production of H₂O₂ and NO₂ −, and the off-gas sparging of the PB-DBD for the production of NO₃ -.
