Advanced oxidation processes involving and were used to compare the degradability and the effect of pH on the oxidation of 1,4-dioxane, Oxidation processes were carried out in a bubble column reactor under different pH. Initial hydrogen peroxide concentration was 3.52 mM in process and 115 g/L (0.65 wt.%) of activated carbon impregnated with palladium was packed in column. 1,4-dioxane concentration was reduced steadily with reaction time in oxidation process, however, in case of process, about of 1,4-dioxane was degraded only in 5 minutes after reaction. Overall reaction efficiency of was also higher than that of process. TOC and were analyzed in order to examine the oxidation characteristics with process. The results of removal efficiency and ratio in process gave that this process could more proceed the oxidation reaction than oxidation process. Therefore, it was considered that advanced oxidation process could be used as a effective oxidation process for removing non-degradable toxic organic materials.
