摘　　要：以活性碳纤维为载体制备了一种吸附性能良好的免疫吸附剂。采用共沉淀法制备单分散性Fe3O4溶胶,将表面清洁的碳纤维在Fe3O4溶胶中进行浸丝,获得磁性涂层碳纤维后,再经过活化偶联即可获得免疫吸附磁性涂层碳纤维。研究了磁性涂层免疫吸附碳纤维对牛血清白蛋白(BSA)的吸附性能。结果表明,磁性涂层在碳纤维表面涂覆均匀,空白活性碳纤维载体对BSA的平均吸附量为9.54mg/g,经活化后的免疫吸附磁性涂层碳纤维对BSA的平均吸附量为84.11mg/g,最高可达到84.60mg/g。An immunoadsorbent with good adsorbability was prepared using activated carbon fiber as the carrier. The magnetically coated CF was obtained after immersing the clean carbon fiber into monodisperse Fe3O4 sol prepared by coprecipitation, and the immunoadsorption magneticlly coated CF can be get after activation and coupling. The BSA adsorption of magnetic immunosorbent carbon fiber was researched. The experiments showed that BSA adsorption of the immunoadsorption magnetically coated CF could reach 84.60 mg/g.
