Abstract: Based on in-situ growth method,magnetite/nickel-iron layered double metal hydroxides (Fe3O4/Ni-Fe-LDHs) hierarchical structures were prepared using Ni-Fe-LDHs sheets growing vertically on the surface of Fe3O4.The adsorption properties of Fe3O4/Ni-Fe-LDHs on organic dyes (methyl orange and methylene blue) were studied.The results showed that the saturation magnetization of Fe3O4/Ni-Fe-LDHs was 41.2emu/g.At room temperature,with the nickel/iron (Ni/Fe) ratio of 2∶1,the adsorption equilibrium time of 48 h and the dosage of 25 mg/L,the adsorption capacities of Fe3O4/Ni-Fe-LDHs for methyl orange and methylene blue were 188mg/g and 175mg/g,respectively.
