The use of advanced oxidation technologies, TiO2 photocatalysis, electron beam irradiation, and sonolysis for the treatment of gasoline oxygenates in aqueous solutions was carried out. The reaction profiles and product distributions for the remediation of these additives by different advanced oxidation technologies were similar. Tert-butyl formate, tert-butyl alcohol, and acetone were the major products. Acetone was degraded slowly relative to MTBE. These studies provided evidence that hydroxyl radical is the predominant species responsible for the degradation of these compounds during these processes. Based on these studies the reaction pathways were defined and reaction mechanisms to explain the formation and disappearance of several intermediate products were proposed.
