摘要
本文通过水热法合成了Fe_3O_4磁性纳米颗粒,采用3-氨丙基三甲氧基硅烷(APTMS)对Fe_3O_4颗粒进行表面修饰,得到氨基化磁性微粒,并表征其性能。并用氨基化Fe_3O_4磁性纳米粒子构建铜离子吸附体系。实验结果表明,Fe_3O_4纳米粒子和功能化Fe_3O_4纳米粒子的磁饱和强度值(M)分别为78和59emu·g^(-1)。最终确定的最优工艺组合为:APTMS@Fe_3O_4添加量2mL,温度30℃,吸附时间15min。
In this paper, Fe3O4 magnetic nanoparticles were prepared by the hydrothermal method. The aminofunctionalized Fe3O4 nanoparticles were modified by APTMS. And characterize its performance. The copper ion adsorption system was constructed by aminated Fe3O4 magnetic nanoparticles. The results showed that the magnetic saturation values of Fe3O4 nanoparticles and funetionalized Fe3O4 nanoparticles were 78 and 59emu· g-1. The optimum process combination was as follows： the addition of APTMS@Fe3O4 was 2mL, the temperature was 30℃ and the time was 15min.
