通过浸渍-碳热法制备出稻壳基活性炭负载纳米Fe3O4颗粒（RH-Fe3O4）,利用光学显微镜、透射电子显微镜、X射线衍射仪等仪器对材料的形貌、物相结构等进行了表征,探讨了RH-Fe3O4在不同条件下对罗丹明B的吸附情况。结果表明在常温常压、p H为6.0±0.1的条件下,0.4 g/L RH-Fe3O4对10 mg/L的罗丹明B的去除率为91.94%,并在100 min内可达到吸附平衡;RH-Fe3O4对罗丹明B的吸附符合Freundlich吸附方程（R2=0.97）;对比稻壳基活性炭和纳米Fe3O4,所合成的RH-Fe3O4具有优越的吸附性能;此外,溶液的初始p H、吸附时间等因素对其吸附效果均有一定影响。

An impregnation/thermo-chemieal conversion approach was developed for preparing nanoscale Fe3O4-10aded activated carbon from rice husk （RH- Fe3O4 ）, Characteristics of the composite partilces, including morphology, structure and surface components, were investigated by optical microscope, TEM and XRD. The adsorption of Rhodamine B by RH - Fe3O4 under different conditions was studied. The results show the removal rate of 10.0 mg/L Rhodamine B aqueous solution by 0.4 g/L RH - Fe304 is 91.94% under room condition and pH = 6.0 ± 0. 1 ; the syste...
