Expanded vermiculite (EVer) was acid activated and silanized in order to obtain suitable substrate’s surface for decoration with iron oxyhydroxides (IO). Obtained activated sample (EVa), was decorated by deposition of either prevailing goethite or amorphous iron oxyhydroxides (AIO) resulting in EV-A and EV-B adsorbent, respectively. Modifications of EVa showed improved adsorption performances when used as adsorbent of lead, chromates and selenites. Adsorption experiments conducted in a batch and column system demonstrated good potential for purification of water contaminated with Pb2+, Cr(VI), and Se(IV). Equilibrium adsorption capacity of EV-A in relation to Pb2+ and Cr(VI) were 48 and 54 mg g-1, respectively, while EV-B showed even better effectiveness for Se(IV) achieving 120 mg g-1 capacity. Regeneration of pollutant saturated adsorbents approved that prepared adsorbents possess fine removal potency even after five adsorption/desorption cycles from 87.58 (for Pb2+/EV-A) to 92.81 % ...(for Cr(VI)/EV-A) of initial adsorption capacity.
