Abstract:To understand the reactions taking place in the dielectric barrier discharge (DBD) plasma system of activated carbon regeneration, the determination of active species is necessary. A method based on High Performance Liquid Chromatography with radical trapping by salicylic acid, has been developed to measure hydroxyl radical (center dot OH) in the DBD plasma reactor. The effects of applied voltage, treatment time, and gas flow rate and atmosphere were investigated. Experimental results indicated that increasing voltage, treatment time and air flow rate could enhance the formation of center dot OH. Oxygen atmosphere and a suitable GAC water content were contributed to center dot OH generation. The results give an insight into plasma chemical processes, and can be helpful to optimize the design and application for the plasma system.
