Abstract
Aqueous sodium sulfate solutions containing dilute concentrations of methyl-t-butylmethylether (MTBE) were electrolyzed to destroy the MTBE. In this treatment, the sulfate / persulfate anion (S2O82-) redox couple servers as the mediator cycle to oxidize MTBE. The solution was circulated through the anode compartment of a two compartment cell, equipped with reticulated vitreous carbon electrodes with100 pores/inch and separated from the cathode compartment by a positively charged ion exchange membrane. The electrolysis successfully reduced the MTBE content of the solutions. The reaction proceeded best when the applied anode potentials were in the range 2 - 3 V vs SCE and the flow rates were 0.100 - 0.125 L/min. Graphite plate, gold screen and platinum screen anodes were briefly tested.
