Abstract:Methy tert-butyl ether (MTBE), a popular organic solvent and gasoline additive, has become a common groundwater pollutant. Numerous isotherm runs were conducted to evaluate the effects of contact time, initial MTBE concentration, raw material/activation, and solution composition on the adsorptive capacity of granular activated carbon (GAC) for MTBE. The adsorption capacity of the carbons employed was in the order of JHBG1>JHBG2>GCN8303 F300>YK>Bamboo. JHBG1 and JHBG2 had the lower consumption amount of activated carbon (0.14 and 0.18g/L) among the six carbon samples during the treatment of low-concentration contaminated groundwater. The adsorption capacity utilization rate from micro column rapid breakthrough technique shows that the GAC adsorption was practical for removing a small quantity of MTBE from groundwater and could provide significant guidance for ectopic remediation for contaminated water.
