Degradation and Removal of Methyl tert-Butyl Ether
نویسندگان
چکیده
Methyl tert-butyl ether (MTBE) has been used in many countries as an octaneenhancing replacement for lead, primarily in midand high-grade gasoline. The prevalent use of MTBE has led to its introduction into environment. MTBE is poorly adsorbed, biologically and chemically stable, making it very persistent in the environment. MTBE has been classified as a possible human carcinogen. Many studies have been carried out to find a better method for the degradation and removal of MTBE in the environment. Activated carbon, clay mineral, resin and zeolite have been used as adsorbents for removal of MTBE. Persulfate, potassium permanganate, Fenton oxidation and photocatalytic oxidation have been studied for chemical degradation of MTBE. In addition, different bacteria have been isolated and identified for biodegradation of MTBE. This review summarizes current knowledge on the adsorption, chemical degradation and biodegradation of MTBE.

Photocatalytic Degradation of Methyl Tert-Butyl Ether (MTBE) from Aqueous Solution: A Review
Nowadays, underground water is the main source of drinking water that contamination to organic pollutants such as MTBE is an important issue. 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 le...
متن کاملRapid Biodegradation of Methyl tert-Butyl Ether (MTBE) by Pure Bacterial Cultures
Two pure bacterial strains capable of rapid degrading methyl tert–butyl ether (MTBE) were isolated from an industrial wastewater treatment plant, identified and characterized. These strains are able to grow on MTBE as the sole carbon and energy sources and completely mineralize it to the biomass and carbon dioxide. The strains were identified as Bacillus cereus and Klebsiella terrigena. Bot...

A microbial consortium that degrades ethyl-tert-butyl ether (ETBE) as the sole source of carbon and energy under aerobic conditions was selected from a gasoline-polluted soil. This consortium consists of a variety of microorganisms with a predominance of filamentous morphology. Degradation of ETBE was found to be solely related to bacterial activity. After prolonged cultivation followed by succ...
