摘要：
The kinetics of oxidation of 1,4-dioxane by persulfate ions in aqueous media was investigated at different temperature, oxidant concentration and pH. Experimental results indicated that 1,4-dioxane degradation follows a pseudo-first-order decay model. Under the experimental conditions the reaction has an activation energy of 21.0 kcal/mol. Temperature and persulfate concentration significantly accelerate the 1,4 dioxane degradation, however, increasing pH (over the range of 3-11) decreased the rate.
