摘要
通过水热法合成纳米Fe_(3)O_(4)/膨胀石墨(Fe_(3)O_(4)/EG),利用X射线衍射(XRD)、扫描电镜(SEM)对样品进行表征,结果表明,延长反应时间都会令复合材料中的Fe_(3)O_(4)纳米粒子自组装成尺度不均的微纳米类球形结构,吸附实验表明复合材料Fe_(3)O_(4)/EG对甲基橙存在明显的吸附作用,石墨对有机分子的强吸附能力对Fe_(3)O_(4)起到了明显的提高作用。
Nano Fe_(3)O_(4)/expanded graphite(Fe_(3)O_(4)/EG)was synthesized by hydrothermal method,and the samples were characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results showed that prolonging the reaction time would cause Fe_(3)O_(4)nanoparticles in the composite material to self assemble into micro nano spherical structures with uneven scales.Adsorption experiments showed that the composite material Fe_(3)O_(4)/EG had a significant adsorption effect on methyl orange,and the strong adsorption ability of graphite on organic molecules significantly improved Fe_(3)O_(4).
