  • 摘要: 选用对空气和人居环境具有污染的悬铃木果毛为基质,通过将四氧化三铁磁性纳米粒子在多巴胺改性悬铃木果毛表面的固载,制备得到具有中空结构的Fe3O4@改性悬铃木果毛复合吸附材料。用X射线衍射仪(XRD)、能谱(EDS)、电子扫描电镜(SEM)、红外光谱(FT-IR)和震动样品磁强计(VSM)等手段对样品进行了表征和分析,考察了Fe3O4@改性悬铃木果毛复合中空纤维对亚甲基蓝的吸附性能。结果表明:通过多巴胺对悬铃木果毛的化学改性,有效促进了反尖晶石型结构的四氧化三铁纳米粒子在其表面的固载,Fe3O4@改性悬铃木果毛复合中空纤维直径约为25.8 μm,其饱和磁化强度为12.51 emu/g, Fe3O4@改性悬铃木果毛对亚甲基蓝的吸附在140 min达到平衡,吸附容量可达12.6 mg/g,吸附动力学符合准二级动力学。
