Alkyl ethers have been introduced into the groundwater in large quantities through leaking fuel tanks and petroleum pipelines and present a serious environmental problem. These ethers, particularly MTBE, have been used as gasoline additives to reduce the level of VOC from the emissions of motor vehicles. These compounds are relatively soluble in aqueous solutions, thus it is difficult to separate and/or treat water polluted by these additives. Detailed product and kinetic studies were performed on the use of advanced oxidation technologies, TiO2 photocatalysis, electron beam irradiation, and sonolysis for the treatment of gasoline oxygenates in aqueous solutions. The reaction profiles and product distributions for the remediation of these additives were similar. Hydroxyl radical was the predominant species responsible for the degradation of these compounds during these processes. The reaction pathways were defined and reactions mechanisms were proposed to explain the formation and disappearance of several intermediate products.
