1,4-dioxane, a possible carcinogen, has been found in the Nakdong river and became a social issue. Synthetic and industrial wastewater containing 1,4-dioxane were treated by catalytic wet peroxide oxidation (CWPO) process. Complete decomposition for synthetic wastewater containing 500 mg/L of 1,4-dioxane was obtained in 10 minutes when 1.0 g/L of copper powder and 196 mM of hydrogen peroxide was applied at 100oC and pH 3. Similarly, an industrial wastewater containing 780 mg/L of 1,4-dioxane was completely decomposed within 30 minutes when 1.5 g/L of copper and 588 mM of hydrogen peroxide was applied, while CODCr was reduced by 60 %. Factors that affecting the experiment were pH, temperature, amount of hydrogen peroxide, and the forms and amount of the catalyst. Ethylene glycol diformate, various forms of organic acids and aldehydes, were produced as by-products of decomposition. Reaction rate was proportionally increased with the dose amount of catalyst. Treatment efficiency was also proportionally increased with the dose amount of hydrogen peroxide. The 1,4-Dioxane decomposition rate of industrial wastes showed the first order reaction with 2.5 × 10−3 s−1 of rate constant.
