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 −.}, title = {Production characteristics of reactive oxygen/nitrogen species in water using atmospheric pressure discharge plasmas}, volume = {55}, year = {2016}, yomi = {タカハシ, カズヒロ and サトウ, コウキ and イトウ, ヒデノリ and カワグチ, ヒデキ} }
