MTBE (Methyl Tert-Butyl Ether) is an oxygen-containing organic compound that has been used in unleaded gasoline. MTBE is a gasoline additive commercially used as an octane enhancer and combustion promoter. Unfortunately, it is recognized that dumping MTBE in nature, contaminates the groundwater and thus its removal is an important process. This research is an experimental-laboratory study, investigating the removal of MTBE using ZnO and CuO. The effect of important operational parameters on the MTBE removal from the groundwater such as pH, changes of initial MTBE concentration, particle size of zinc and copper oxide nanoparticles, and UV irradiation time was studied as well. The results showed that using copper oxide nanoparticles for MTBE removal yielded higher efficiency compared with using zinc oxide nanoparticles. The increase in nano-oxide particle size led to an enhancement in MTBE removal efficiency. This study has shown that the yield of MTBE removal from contaminated water can be expected to be higher in the presence of UV irradiation, acidic pH, high initial concentration using copper and zinc nanocatalyst.
