“…Unfortunately, this additive has been found present in groundwater and surface water due to leakages from car or underground fuel tanks creating a serious environmental problem due to its refractory properties to degrade when releases into the environment. [8][9][10][11] In search of a suitable and efficient method to degrade MTBE, there have been many applications of advanced oxidation processes with very promising results. Within this technology is found the Catalytic Wet Air Oxidation (CWAO).…”

“…Among the oxygen-containing compounds, methyl tert-butyl ether (MTBE) is the most commonly used gasoline additive because of its low cost and ease of production and blending (Fayolle et al, 2001;Kharoune et al, 2001). However, because of the large amount of MTBE used, contamination has occurred in groundwater, surface water, and air (Juhler and Felding, 2003;Ayotte et al, 2005;Kolb and Püttmann, 2006;Toran et al, 2003;Schmidt et al, 2004;Rosell et al, 2006;Guillard et al, 2003;Lin et al, 2005). Methyl tert-butyl ether has been demonstrated to be an animal carcinogen.…”

The objective of this study was to evaluate the feasibility of using ferrous ion-activated persulfate oxidation to remediate groundwater contaminated with methyl tert-butyl ether (MTBE). In this study, batch experiments were conducted to evaluate the effects of various factors on the efficiency of MTBE degradation including persulfate concentrations, ferrous ion concentrations, and persulfate coupled with hydrogen peroxide. Results show that ferrous ion-activated persulfate oxidation was capable of degrading MTBE efficiently. Persulfate and ferrous ion concentrations correlated with MTBE degradation rates. However, excess addition of ferrous ion resulted in decreased MTBE degrading rates most likely because of competition for sulfate free radicals between ferrous ion and MTBE. Two main byproducts of MTBE degradation, tert-butyl formate and tert-butyl alcohol, were detected in the experiments; both were, however, subsequently degraded. Results of sulfate analysis show that proper addition of ferrous ion could prevent unnecessary persulfate decomposition. Water Environ. Res., 81, 687 (2009).

“…The mass transfer coefficient enhancement of CNIM-f varied from 10% to 14%, compared to the plain membrane. The activation energy (Ea) for MTBE was calculated from the equation (5). The activation energies of PTFE membrane, CNIM-f and GOIM were 9, 8.6 and 7.9 kJ/mol, respectively.…”

“…Over 20 million tons of methyl tert-butyl ether (MTBE) is produced and used as a fuel additive around the world every year, and it has contaminated ground and surface water all across the globe [1,2]. Its impact on the environment and human health has been a great concern in the USA and other countries as well [3][4][5][6][7][8][9]. MTBE is highly water soluble, has a low Henry's Law constant and low sorption constants [2].…”

Removal and Recovery of Methyl Tertiary Butyl Ether (MTBE) from Water Using Carbon Nanotube and Graphene Oxide Immobilized Membranes

Methyl tert-butyl ether (MTBE) is a widely used gasoline additive that has high water solubility, and is difficult to separate from contaminated ground and surface waters. We present the development in functionalized carbon nanotube-immobilized membranes (CNIM-f) and graphene oxide-immobilized membranes (GOIM) for enhanced separation of MTBE via sweep gas membrane distillation (SGMD). Both types of modified membranes demonstrated high performance in MTBE removal from its aqueous mixture. Among the membranes studied, CNIM-f provided the best performance in terms of flux, removal efficiency, mass transfer coefficients and overall selectivity. The immobilization f-CNTs and GO altered the surface characteristics of the membrane and enhanced partition coefficients, and thus assisted MTBE transport across the membrane. The MTBE flux reached as high as 1.4 kg/m2 h with f-CNTs, which was 22% higher than that of the unmodified PTFE membrane. The maximum MTBE removal using CNIM-f reached 56% at 0.5 wt % of the MTBE in water, and at a temperature of 30 °C. With selectivity as high as 60, MTBE recovery from contaminated water is very viable using these nanocarbon-immobilized membranes.
