    Abstract

    Granular mesoporous silica SBA-15 (GMS) synthesized by a new and facile one step method was investigated to remove a series of pharmaceutical compounds from aqueous solutions. Characterization results obtained from TEM, XRD, and surface and porosity analyzer reveal that GMS synthesized by using inorganic and organic binder has similar pore properties with the powder-type mesoporous silica SBA-15 and does not severely reduce the Brunauer-Emmett-Teller (BET) surface area and pore volume by preventing destruction of the pores after granulation step through new synthesis method. Evaluation of GMS as an adsorbent based on adsorption kinetic, isotherm, and effect of pH shows the great adsorption capacity for selected 12 selected pharmaceuticals removal in aqueous solution. In addition, the adsorption and regeneration efficiency of GMS was maintained for given adsorption-regeneration cycles. Moreover, the column experiment to remove pharmaceuticals in industrial pharmaceutical wastewater revealed that GMS has a great potential for its real field application.
