“…Other charcoal types might show better capacities for MTBE, e.g. coconut carbons [15,16], however, the F300 is typically used in German waterworks and has therefore been investigated in this study.…”

“…Granular activated carbon (GAC) adsorption is a widely used technology for treating water contaminated with many taste-and odor-causing organics and synthetic organic chemicals, either independently or coupled with biological degradation (Suffet and Wable, 1995;El Diwani et al, 2009). Some researches have reported that GAC could successfully remove MTBE from contaminated water (Wilhelm et al, 2002;Shih et al, 2003;Sutherland et al, 2004) mainly due to its well developed porous internal structure and large surface area (Yang and Al-Duri, 2005). The systemic investigation on the kinetic and mechanism of MTBE adsorption has not reported.…”

AB STRACT:The adsorption of methyl tert-butyl ether by granular activated carbon was investigated. The experimental data were analyzed using the Freundlich isotherm and the Langmuir isotherm. Although equilibrium data were found to follow Freundlich isotherm model, it were fitted better by the Langmuir model with a maximum adsorption capacity of 204.1 mg/g. The kinetic data obtained at different concentrations were analyzed to predict the constant rate of adsorption using three common kinetic models: pseudo-first-order, pseudo-second-order equation and intraparticle diffusion equation. The pseudo-second-order model was suitable for describing the adsorption kinetics for the removal of methyl tert-butyl ether from aqueous solution onto granular activated carbon. Both the Lagergren first-order rate constant k 1 and pseudo-second-order rate constant k 2 decrease with increasing initial concentrations of methyl tert-butyl ether and the intraparticle diffusion rate constant k p shows the reverse characteristic. Analysis of sorption data using a boyd plot confirmed that external mass transfer is the main rate-limiting step at the initial stage of adsorption. Results illustrate that granular activated carbon is an effective adsorbent for methyl tert-butyl ether and also provide specific guidance into adsorption of methyl tert-butyl ether on granular activated carbon in contaminated groundwater.

However, poor removal efficiency may be observed in applying carbon adsorption process, especially when other SOCs co-exist with MTBE.…”
