  • 摘要: 以介孔氧化硅SBA-15为硬模板，采用三氯化铁与蔗糖同步浇筑法制备磁性介孔碳材料.扫描电镜、透射电镜、比表面积和振动磁强计等分析表明，该材料具有有序的介孔孔道和较好的磁分离性能.考察其对亚甲基蓝（MB）和日落黄（SY）的吸附性能，结果发现溶液的pH对吸附两种染料有显著的影响，阳离子染料亚甲基蓝随着溶液pH的增大吸附量显著升高，而阴离子染料日落黄则相反.由Langmuir吸附等温模型拟合出亚甲基蓝、日落黄的最大吸附容量分别为473.9 mg·g-1和434.8 mg·g-1.该磁性介孔材料在染料污染物的去除方面具有较好的应用潜力.
    Abstract: Magnetic mesoporous carbon (MMC) material was synthesized with ferric chloride and sucrose synchronous pouring into mesoporous silica SBA-15 as hard template. Characterization with TEM,SEM,BET,and VSM demonstrated that the mesoporous material has ordered channels and superparamagnetism. The resulted MMC material was used as adsorbent to remove methylene blue(MB) and sunset yellow(SY) from water. The results showed that solution pH had significant effect on the adsorption. As a cationic dye,the adsorption capacity of MB increased obviously with the increase of pH,while the adsorption of SY(anion dye) presented the contrary results. The maximum adsorption capacity calculated from Langmuir adsorption isotherm for MB and SY was 473.9 mg·g-1 and 434.8 mg·g-1,respectively. The MMC material exhibited good potential for the removal of dye pollutants.
