Effect of Ultraviolet Light on the Efficiency of Nano Photo-Catalyst (UV/ CNTs/TiO2) Composite in Removing MTBE from Contaminated Water

Abstract—In this study, the removal efficiency of methyl tertiary butyl ether (MTBE) by: (1) UV-Titanium dioxide (UV/TiO2), (2) UV-Carbon Nanotubes (UV/CNT) and (3) 5% TiO2 impregnated on CNTs surface (UV/CNTs/5%TiO2) 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/TiO2 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/TiO2 were much lower than that of UV/TiO2.
