摘　　要：利用3-(2,3-环氧丙氧)丙基三甲氧基硅烷(EPPTMS)与正硅酸乙酯在Fe_3O_4磁性纳米粒子(MN)表面发生共聚反应,制得表面富有含氧活性基团的复合磁性纳米吸附剂(EPPTMS-MN),研究EPPTMS-MN对铀的吸附性能及其机理,结果表明,EPPTMS-MN是良好的铀吸附材料。The syntheses of a novel nano-adsorbent for uranyl ions by copolymerizing of tetraethyl orthosilicate and 3-aminopropyltriethoxysilane on the surface of magnetic microparticle （ Fe3O4 ）. The adsorption abilities and mechanisms of the new adsorbent for the uranyl ions were studied through a series of adsorption experiments and mathematical models. The results indicate that this compound adsorbent is good uranium adsorption material.
