Abstract
The catalysis of various granular activated carbons (GAC) was investigated with the combination of pulsed streamer discharge in the non equilibrium plasma water treatment reactor. The results showed that the removal efficiency of Methyl Orange (MO) could be increase significantly and the chemical oxygen demand (COD) can be removed effectually in the presence of GAC1 and GAC3 due to their catalysis and adsorption. The basic functional groups (BFG) on GAC surface displayed catalytic activity because the catalytic decomposition of ozone generated hydroxyl radicals in aqueous phase. The catalytic properties were favored by both the basicity of the carbon surface and the higher specific surface area (SBET) of carbon.
