Dielectric Barrier Discharge Plasma Activates Persulfate to Degrade Norfloxacin: Mechanism and Degradation Pathways

摘要

In these studies, sodium persulfate was activated by atmospheric pressure non-thermal dielectric barrier discharge (DBD) plasma to degrade norfloxacin in aqueous solution. Our results showed that the degradation of norfloxacin could be remarkably enhanced with the addition of sodium persulfate to the norfloxacin solution treated by DBD in an oxygen atmosphere. The relationship between the degradation efficiency and the concentration of sodium persulfate is examined, and the possible degradation reaction pathways and mechanisms are discussed.
