以酚醛树脂为碳源,F127为模板剂,硝酸铁为铁源,采用软模板路线,一步合成了载铁有序介孔碳(Fe/OMC)复合材料.采用XRD、N2吸附、TEM手段对材料的结构进行了表征,结果表明Fe/OMC复合材料具有高度有序的二维六方介孔结构,孔径均一.在此基础上,比较了未载铁介孔碳(OMC)与Fe/OMC对对氯酚的吸附性能.在初始浓度为1.20×10-4,吸附剂用量为0.5g/L的条件下,OMC对对氯酚的去除率为46.6％,Fe/OMC对对氯酚的去除率94.6％,去除率约为OMC的2倍.采用Langmuir等温吸附线对吸附结果进行拟合.结果表明两种材料对氯酚的吸附行为均能较好地拟合Langmuir方程,OMC材料对4-CP的饱和吸附量为82mg/g,Fe/OMC材料对4-CP的饱和吸附量为284mg/g,Fe/OMC材料的饱和吸附容量约为OMC的3倍.
