Abstract

Abstract:

AbstractThe CMK-3-130 exhibits the largest adsorption capacity than CMK-3-100 and CMK-3-150. Mesoporous carbon sieves were prepared from SBA-15 materials at different temperatures. This allows the synthesis of mesoporous carbons sieves with pore dismeters in the range from 3.7 nm(CMK-3-100) to 6.3 nm(CMK-3-150).The mesoporous carbons sieves were studied in the adsorption of VB12 from water solutions. The maximal adsorption capacity of 412.5 mg/g was found for CMK-3-130, which is probably a consequence of its highly ordered mesostructures and larger pore.

Key words: SBA-15; Mesoporous carbon; Adsorption behavior; VB₁₂
