Influence of Pulse Discharge on Pore Structure and Surface Properties of Activated Carbon

Influence of pulse discharge on pore structure and surface properties of granular activated carbon (GAC) were investigated with the combination of pulsed streamer discharge in the non equilibrium plasma water treatment reactor. The results showed that the textural properties of all three GAC were modified only slightly in pulse streamer discharge; however, their chemistry surface properties were influenced strongly. Both the acid and basic functional groups on the carbon surface could be increased. The results of repeated use indicated that GAC can be efficiently regenerate in situ during combined treatment.
