采用纳米共铸法将磁性纳米粒子包埋到有序介孔炭的骨架中,制成含有磁性纳米粒子的有序介孔炭(Fe/OMCs).实验通过氮气吸附、扫描电镜、X射线衍射、磁性测试等手段对Fe/OMCs进行了系统的表征.研究表明,Fe/OMCs基本保持了有序介孔结构,磁性粒子在材料中以纳米α-Fe粒子的形式存在,并且具有超顺磁特性.盐酸四环素(TH)在Fe/OMCs上的吸附研究表明,Fe/OMCs的介孔表面积和介孔孔容是决定TH吸附量的关键因素.脱附动力学研究表明,Fe/OMCs的孔尺寸是影响脱附速率的关键因素,孔径越大,TH的脱附速率就越大.
Nanocrystalline co-casting method was used to embed the magnetic nanoparticles in the framework of ordered mesoporous carbon to prepare ordered mesoporous carbon (Fe / OMCs) containing magnetic nanoparticles.The experiment was characterized by nitrogen adsorption, scanning electron microscopy, X-ray diffraction , Magnetic measurements and other means of Fe / OMCs were systematically characterized.Research shows that the Fe / OMCs basically maintained an ordered mesoporous structure, the magnetic particles in the material in the form of nano-α-Fe particles, and with super paramagnetism The adsorption behavior of tetracycline (TH) on Fe / OMCs showed that the mesopore surface area and mesopore volume of Fe / OMCs were the key factors determining the TH adsorption capacity.The desorption kinetics showed that the pore size of Fe / Size is the key factor affecting the desorption rate. The larger the pore size, the greater the desorption rate of TH.
