dc.description.abstractIn this study ionic liquid mediated sol-gel silica adsorbents were prepared and characterizedin order to investigate the sorption performances for the removal of Cr (VI) ions fromaqueous solutions. High extracting ability of ILs was combined with the surface properties ofsilica substances by confining ILs in porous matrices. Commercial (Aliquat 336® andEMIMTf2N) and synthesized ([A336][NO3]) ionic liquids were incorporated directly by solgel process. Silica based adsorbents were being initiated with silica precursor (TEOS), water,alcohol and ionic liquid hydrolysis in the presence of an acid catalyst then completed with acondensation reaction. Chemical and morphological characterizations of prepared adsorbentshave been investigated by FTIR, SEM and BET analysis. The materials exhibited averagepore diameter of 2 nm, pore volume of 0.3 cm3/g and BET surface area of 300–600 m2/g.The sorption behaviors of adsorbents have been investigated by using a series of batchsorption studies. Cr(VI) sorption percentages of the adsorbents were enhanced by containingILs up to 99% with the adsorption capacity of 31.74 mg/g. It can be concluded that sorptionof Cr(VI) ions from aqueous solution by sol-gel silica based adsorbents containing Aliquat336 takes place favorably and these type of adsorbents are promising agents in theadsorption processes.en_US
