3. RESULTS & DISCUSSION
(1.) H2O2, NO2- and NO3- in water
H2O2 and NO2- are not produced by the PB-DBD off-gas sparging, so that these species may beproduced by short-lifetime species such as OH in plasma.
H2O2 concentration in the pulsed discharge and the corona discharge decreases when NO3- is produced, because OH may be consumed in NO3- is production
Pulsed discharge is effective to produce H2O2 and NO2-, and PB-DBD off-gas sparging is effective to produce NO3-.
