摘要：以SBA-15为模板,蔗糖为碳源,硝酸铁辅助催化合成磁性石墨化介孔碳复合材料(Fe/GMC).利用X射线粉末衍射(XRD)、透射电子显微镜(TEM)、N2吸附-脱附(BET)、拉曼光谱等对反应产物进行了表征.硝酸铁辅助催化可以在较低碳化温度(900°C)下实现介孔碳的部分石墨化,并同步生成磁性Fe3O4颗粒,合成的产物比表面积大、孔道有序、磁性强.运用紫外-可见(UV-Vis)光谱考察了该复合材料对中药红花色素废水的吸附特性,复合材料的吸附速率快、吸附量高,具有良好的脱色效果并能实现吸附剂的快速固液磁分离.
Magnetically graphitic mesoporous carbon （Fe/GMC） was synthesized,using SBA-15 as a template and sucrose as a carbon source,with the assistance of ferric nitrate impregnation.The properties of the products were characterized using powder X-ray diffraction （XRD）,transmission electron microscopy （TEM）,N 2 adsorption-desorption （BET）,and Raman spectroscopy.The impregnation of Fe 3 ＋ promoted the partial graphitization of ordered mesoporous carbon at low temperature （900 °C）,and resulted in the production of magnetic Fe 3 O 4 particles.These complex materials possessed an ordered mesoporous pore structure,large surface area,and magnetic properties.The adsorption properties of Fe/GMC for traditional Chinese medicine wastewater were studied in detail using UV-Vis spectroscopy.The results showed that the Fe/GMC materials displayed rapid adsorption,and had a high adsorption capacity.Fe/GMC could be used as an absorbent for the highly efficient removal of pigments from Carthamus tinctorius flowers via rapid solid-liquid magnetic separation.
