Treatment of MTBE-Contaminated Water Using Fenton=s Reagent: Effects of Single and Multiple Addition of Reagent on the Overall Reaction Efficiency.
Abstract:Previous studies indicate that under certain reaction conditions, Fenton's Reagent (FR) can be used for the removal of low concentrations of MTBE in water. However, a better understanding of the Fenton reaction is necessary for the optimization of this technology. Therefore, this study focuses on the effect of the method of addition of FR on the overall efficiency of the reaction. Single and multiple addition of FR to the reaction solution were tested. Initially, an MTBE concentration of 2 mg/L was treated with FR added in a single dose with a concentration equivalent to a [FR:MTBE] molar ratio of 10:1 at pH of 3.0 (Exp.1). Exp. 2 investigated the effect of an extra dose of the same concentration of FR added at t=30 min and finally, Exp. 3 studied the results of using an [FR:MTBE] of 20:1 added in a single dose. Exp.1 was a control test, while Exps.2 and 3 were performed to establish the effect of using a [FR:MTBE] molar ratio of 20:1 with multiple and single dose respectively.
