“…[3][4][5] are analyzed for the reaction kinetics at various initial concentrations of MTBE, H 2 O 2 , and TiO 2 . The rate constants, half-lives along with regression coefficients for the linearalized pseudo first-order kinetic model are summarized in Table 1 for UV/H 2 O 2 and Table 2 for UV/TiO 2 .…”

“…The United States Environmental Protection Agency (EPA) has classified MTBE as a suspect human carcinogen, and suggested concentration limit of 20-40 mg/l for MTBE in drinking water. The U.S. EPA has banned the use of MTBE as a gasoline additive since May 2006 [5]. Reported MTBE concentrations in the environmental waters varied in the range of g/l to the lower mg/l [1,2,4,6].…”

“…Benzene, toluene, ethyl benzene and xylene (BTEX) as well as methyl tertiary butyl ether (MTBE) are organic compounds frequently encountered in groundwater. MTBE is a fuel additive that enhances octane rating and helps lower harmful emissions [2], [3], [4]. Its presence in the environment, particularly water, is however an issue of concern due to its potential human health implications.…”

Abstract-In this study, the removal efficiency of methyl tertiary butyl ether (MTBE) by: (1) UV-Titanium dioxide (UV/TiO 2 ), (2) UV-Carbon Nanotubes (UV/CNT) and (3) 5% TiO 2 impregnated on CNTs surface (UV/CNTs/5%TiO 2 ) was investigated. Two types of UV irradiation were utilized in this study namely: UVA irradiating at wavelength of 365nm and UVC irradiating at a wavelength of 254 nm. Dosage of 20 mg of nano materials was used in these experiments. The fate of MTBE's main degradation by-products were also investigated in this study. Results of the study showed that MTBE removal in the dark was very low for the three types of nano materials under the study conditions used. However, appreciable removal of MTBE was observed when using UV/TiO 2 for both types of UV lights, with UVC showing slightly better than UVA. On the other hand, the removal of MTBE by UV/CNTs and UV/CNTs/TiO 2 were much lower than that of UV/TiO 2 .

“…However, in 1997, the USEPA Office of Water issued a health advisory on MTBE. This advisory was issued to provide guidance to water suppliers whose source waters had been impacted MTBE can be removed from contaminated water using different treatment methods (Sutherland et al 2004;Kuburovic et al 2007). Conventional treatment of MTBEcontaminated groundwater is inefficient and unsatisfactory.…”

In this study, the removal of methyl tertiary-butyl ether (MTBE) from contaminated groundwater using advanced oxidation technology was investigated. The UV/H(2)O(2) treatment process was applied to remove MTBE from two Saudi groundwater sources that have different quality characteristics with regard to their contents of inorganic species such as chloride, bromide, sulfates and alkalinity. MTBE was spiked into water samples collected from the two sources to a concentration level of about 250 microg/L. A 500 mL bench-scale forced-liquid circulation photoreactor was used to conduct the experiments. Two different UV lamps were utilized: 15 Watt low pressure (LP) and 150 Watt medium pressure (MP). Results of the study showed that the UV/H(2)O(2) process removed more than 90% of MTBE in 20 minutes when the MP lamp was used at an MTBE/H(2)O(2) molar ratio of 1:200. The results also showed that groundwater sources with higher levels of radical scavengers such as alkalinity, bromide, nitrate and sulfate showed lower rate of MTBE removal.
