The kinetics of oxidation of 1,4-dioxane by persulfate ion with Ag+ in aqueous solutions at various temperatures and concentrations of S2O82-, Ag+ and H2SO4, were investigated. Experimental results indicate that 1,4-dioxane degradation follows a pseudo-firstorder decay model and that reaction rate significantly accelerate by increasing temperature and concentration of oxidant, sulfuric acid and Ag+ ions up to 0.46 mM; for the range from 0.46-0.70 mM of Ag+ ions the reaction rate remains constant and at higher concentrations the reaction rate decreases. It was possible to degrade approximately 100% of 1,4-dioxane in less than one hour with the following conditions: [Ag+] = 0.46 mM, H2SO4] = 0.30 M and from a concentration of 25 mM Na2SO4.Downloads
