Abstract

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.
