Regarding adsorption-based processes, activated carbons (ACs) and other carbonaceous materials have been widely characterized as suitable adsorbents for the removal of CEs from the gas phase and from aqueous solution. Zeolites, crystalline microporous materials having a tetrahedral framework structure, have been investigated altogether less frequently than carbons. Nevertheless, a number of experimental studies have addressed the adsorption of TCE and PCE using zeolites.
