摘　　要：本文用共沉淀法和催化活化法分别制备出磁性微粒和磁性流体。用活性炭与磁粉按不同的比例配制反应以及与磁流体混合配制反应这两种不同的方法,制备出磁粉/活性炭复合材料。用扫描电镜观察制备前后的微观组织;用磁强计测定样品的磁特性;通过碘吸附值法测定磁粉/活性炭复合材料吸附性能,并根据Freundlich平衡方程,计算出不同磁粉/活性炭复合材料的碘吸附值。Magnetic liquid and magnetic powder were prepared by co-precipitation method and catalytic activated method respectively.The magnetic powder/activated carbon compounds were achieved by two different methods,mixed activated carbon with magnetic powder and mixed activated carbon with magnetic liquid.The microstructure of activated carbon were presented by SEM.Magnetic characteristic was studied by magnetic strength instruments.Adsorptive capability was measured by adsorption iodine method,and based on Freundlich equilibrium equation adsorptive iodine of adsorbents was got.
