Study on Synthesis and Adsorption Property of Fe3O4/LDHs Composites

Keywords： layered double metal hydroxide (LDHs) , Fe3O4 , composite , adsorption property

分别采用两种方式(一步合成法和二步合成法)在Fe3O4表面生长层状双金属氢氧化物(LDHs),得到了Fe3O4/LDHs复合材料.利用X-射线衍射、电子显微分析、红外光谱和交变梯度磁强计等测试方法研究了LDHs和Fe3O4的复合方式对复合材料形貌、粒径、结晶性、磁性能和吸附性能的影响.同时对比分析了LDHs和Fe3O4/LDHs复合材料对Cr(Ⅵ)离子的平衡吸附规律.结果表明,采用一步合成法制备的Fe3O4/LDHs复合材料具有良好的磁性能和吸附性能.
