Degradation of Substituted Phenols in a hybrid gas-liquid electrical discharge reactor

Popis výsledku v původním jazyce

Non-thermal plasma induced decomposition of ortho-, meta-, and para- isomers of hydroxy-, chloro-, and nitro- phenols in water was investigated using the hybrid series gas-liquid electrical discharge reactor that generates gas phase discharge above the water surface simultaneously with the electrical discharge directly in the liquid. Degradation of substituted phenols was evaluated for two gas phase compositions, pure argon and pure oxygen, above the aqueous solution. Removal of all phenols was found tofollow first order kinetics. Hydroquinone was the most reactive among substituted phenols under oxygen atmosphere, whereas in argon the most reactive were 4-chlorophenol and 2-nitrophenol. Electrophilic attack by hydroxyl radicals and ozone were determined to be the main oxidation pathways for degradation of phenols in the hybrid series reactor under argon and oxygen atmospheres, respectively.
