Decomposition efficiency of 1,4-dioxane in water was examined by sonophotocatalytic method through comparison of TiO2 and HF-treated TiO2. 1,4-Dioxane is effectively decomposed by combining sonolysis and photocatalysis. This synergistic effect is attributable to effective enhancement of photocatalysis by sonolysis. HF treatment of TiO2 surface enhances its absorption capabilities for both 1,4-dioxane and ethylene glycol diformate (EGDF), while improving the overall decomposition rate of 1,4-dioxane by sonophotocatalytic treatment.
