【摘要】 以三嵌段共聚物聚环氧乙烯-聚环氧丙烯-聚环氧乙烯(F127)为结构导向剂,甲阶酚醛树脂为碳前驱体,通过溶剂挥发诱导自组装(EISA)的方法制备介孔碳材料,通过X射线衍射(XRD),氮气吸脱附分析表征其结构及性质.将该材料用于去除水相中对氯苯酚和对氯苯胺,表现出很好的吸附性能,其饱和吸附量分别达到220mg/g和210mg/g,与活性炭相比较,在污染物浓度较低时显示出更优越的吸附能力.更多还原

【Abstract】 The ordered mesoporous carbon was synthesized with triblock copolymer F127 as the structure directing agent,low-polymerized phenolic resins as carbon sources via the evaporation induced self-assembly route.Small angle X-ray diffraction and nitrogen sorption techniques proved the structure and characters of the material.To remove p-chlorophenol and p-chloroaniline from their aqueous solution,the mesoporous carbon showed great adsorbed ability,with the saturated adsorbed amounts as high as 220 mg/g and 210 mg/g,respectively,showing superiority over the autiqated carbon at very low concentration of contaminants.更多还原
