【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.更多还原

【Abstract】 The 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.更多还原
