摘要：MTBE (Methyl Tert-Butyl Ether) is an oxygen-containing organic compound that has been used inunleaded gasoline. MTBE is a gasoline additive commercially used as an octane enhancer and combustionpromoter. Unfortunately, it is recognized that dumping MTBE in nature, contaminates the groundwaterand 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 parameterson the MTBE removal from the groundwater such as pH, changes of initial MTBE concentration, particlesize of zinc and copper oxide nanoparticles, and UV irradiation time was studied as well. The resultsshowed that using copper oxide nanoparticles for MTBE removal yielded higher efficiency comparedwith using zinc oxide nanoparticles. The increase in nano-oxide particle size led to an enhancement inMTBE removal efficiency. This study has shown that the yield of MTBE removal from contaminatedwater can be expected to be higher in the presence of UV irradiation, acidic pH, high initial concentrationusing copper and zinc nanocatalyst.
