摘要

具有高比表面积、大孔容的铁磁性有序介孔炭(Fe/OMCs)对含染料废水的处理提供了一种简单有效的方法。采用苯酚树脂作炭源

三嵌段共聚物F127为模板剂

正硅酸乙酯为硅前驱体

硝酸铁为磁源

通过软模路线合成了Fe/OMCs。利用X射线衍射仪(XRD)

氮气吸附仪

透射电镜(TEM)和综合物性测试仪研究了硝酸铁加入量对Fe/OMCs的相态、孔结构参数和磁性的影响;并以亚甲基蓝(MB)为染料探针分子

研究了Fe/OMCs对MB的吸附行为。结果表明材料有序性、比表面和孔容随着硝酸铁加入量的增加而降低

而饱和磁化强度明显增强。Fe/OMCs对MB有快速吸附能力

其行为符合Sips吸附方程。

Abstract

Magnetic Fe-containing ordered mesoporous carbons(Fe/OMCs)with high surface area and large pore volume provide an easy and effective way for the treatment of dye in waste water.Fe/OMCs were synthesized by the soft-template route

wherein phenolic resin was used as a carbon precursor

triblock copolymer F127 as a template agent

tetraethylorsilicate(TEOS)as a silica precursor and hydrated iron nitrate as an iron source.The effects of Fe(NO3)3?9H2O loading on the morphology

structural parameters

and magnetic properties of the Fe/OMCs were evaluated by X-ray diffraction(XRD)

N2 sorption analysis

transmission electron microscopy(TEM)and physical property measurements.By using methylene blue(MB)as model dye

the adsorption of MB on the obtained Fe/OMCs was investigated.The experimental results showed that the ordering

specific surface area and total pore volume decreased with the increase of Fe(NO3)3?9H2O loading.The Fe/OMCs had fast adsorption ability for MB.The adsorption of MB on the obtained Fe/OMCs followed the Sips adsorption equation and the corresponding parameters were obtained.
