摘要:

摘要利用SBA-15为模板, 在不同温度下合成了孔径大小在3.7(CMK-3-100)和6-3 nm(CMK-3-150)之间的介孔碳, 以其作为吸附剂, 研究了它们在水溶液中对VB12的吸附作用. 结果表明, CMK-3-130与CMK-3-100和CMK-3-150相比, 表现出对VB12最大的吸附能力(吸附能力为412.5 mg/g), 这是因为它有比较高的有序结构和比较大的孔容.

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
