FELIX-NAVARRO, Rosa María; LIN-HO, Shui Wai; BARRERA-DIAZ, N.  e  PEREZ-SICAIROS, Sergio. Kinetics of the Degradation of 1,4-Dioxane Using Persulfate. J. Mex. Chem. Soc [online]. 2007, vol.51, n.2, pp.67-71. ISSN 1870-249X.

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.

Palavras-chave : 1,4-dioxane; persulfate; degradation; kinetics.
