A general review on the application of adsorption and oxidation combined processes on methyl tert-butyl ether removal

The extensive use of methyl tert-butyl ether as a gasoline additive has produced environmental pollution globally due to its high solubility and recalcitrance. Due to the persistent pollution and potential toxicity, the development of technology for methyl tert-butyl ether removal has become a priority. Single technologies have limitations that can be addressed through the combination of various processes. Here, we provide a comprehensive overview of the mechanism and application of adsorption and oxidation combined process to remove methyl tert-butyl ether. The materials commonly used in combined process, such as zeolite and activated carbon, are compared. The physical and chemical properties and functions of different materials are explored. Moreover, the pretreatment mechanism and the effects of acid reagents are discussed. Furthermore, various conditions affecting the removal efficiency, such as temperature, pH, coexisting anions, are analyzed. Ultimately, the integration of adsorption and oxidation processes is promising for efficient degradation of methyl tert-butyl ether.
