One of the suitable methods for these types of pollutants is the advanced oxidation methods. Advanced oxidation processes (AOPs) are involved in the production of highly reactive hydroxyl radicals that oxidize organic matter such as MTBE and even lead to its full mineralization. The use of light in the presence of catalysts is one of the methods of advanced oxidation processes. Photocatalytic methods widely used for a wide range of toxic and none degradable pollutants. Recent advances in the fabrication and characterization of Nano scale materials have extensively developed research into methods for the preparation of highly effective Nano-sized catalysts for the removal of chemical contaminants. This review article discusses the work on the photo catalysis of MTBE in water using different types of photo catalysts.</span></span></div> <br> <span dir="RTL"></span> Photo catalysis, Nanoparticles, MTBE removal, AOPs, Water pollution 2 7 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-139-1&slc_lang=en&sid=1 Ali Assadi assadi@zums.ac.ir 10031947532846009501 10031947532846009501 No Department of Environmental Health Engineering, School of Public Health, Zanjan University of Medical Sciences, Zanjan, Iran.
