羧甲基纤维素钠辅助磁性Fe_3S_4纳米复合物的合成及其吸附与吸波性质研究

Preparation of CMC-Na-assisted Fe_3S_4 Magnetic Nanocomposites and Their Adsorption and Microwave Absorbing Properties

以羧甲基纤维素钠(CMC-Na)为模板,采用简单温和的水热法制备了一种薄片状含碳Fe3S4纳米复合物,并探讨了反应时间和反应温度的影响。采用X射线衍射、扫描电镜、透射电镜、FT IR、振动磁强计和UV-Vis对材料进行了表征。结果表明,这种纳米复合材料在常温下具有较好的吸波性质和对污水中亚甲基蓝染料的吸附作用。

Carbonaceous lamelliform Fe3S4 nanocomposites were synthesized via a facile hydrothermal method in the presence of sodium carboxymethylcellulose（ CMC-Na） and characterized by XRD,SEM,TEM,FT IR,VSM,and UV-Vis spectrometry. The results indicated that the formation of the samples depends strongly upon the reaction temperature and time. The as-prepared nanocomposites have efficient adsorption abilities for methylene blue（ MB） in waste water and microwave absorption property at room temperature.
