A study on the catalytic ozonation of 1,4-dioxane

Advanced oxidation involving O₃/catalyst was used to eliminate 1,4-dioxane and to compare the degradability of dioxane-contaminated water with O₃ only and O₃/H₂O₂. Oxidation experiments were carried out in a bubble column reactor under different oxidation sources such as O₃ only, O₃/ H₂O₂, and O₃/catalyst. The O₃/H₂O₂ and O₃/catalyst process effectively converted dioxane to more biodegradable intermediates. On the economic aspect, O₃/catalyst process could be reduce the treatment cost of 1,4-dioxane instead of O₃/H₂O₂ process which have high cost of H₂O₂.
