The ability of zeolite adsorbents to remove CEs from aqueous solution has received considerable attention. To limit the co-adsorption of water, these investigations typically focused on highly siliceous zeolites. For example, Silicalite-1 membranes grown on steel supports were proposed for the removal of trans-1,2-DCE and TCE from water. Other authors used zeolites as "dual-function" materials that allow for a catalytic decomposition of the CEs after adsorption. In a very recent pilot-scale study by Georgi and co-workers, a Feloaded MFI-type zeolite was used together with an AC adsorber for the removal of hydrophilic chlorinated hydrocarbons including VC from contaminated groundwater. The zeolite could be regenerated several times by flushing with H2O2, degrading the adsorbed contaminants in a Fenton-like reaction. Since the zeolite removed those compounds that break through the AC early, the operation time of the AC adsorber could be expanded significantly. This last example shows that zeolites may not necessarily be attractive as a stand-alone solution for contaminant removal, not least due to their high cost, but that usage in conjunction with other materials and/or techniques may constitute an attractive option.
