Paper Title:
Fe3O4/ Rectorite Composite: Preparation, Characterization and Absorption Properties from Contaminant Contained in Aqueous Solution
  Abstract

A series of Fe3O4/rectorite composite were prepared with chemical coprecipitation method by adding magnetic Fe3O4 particles into rectorite as different weight ratios. The samples were tested and characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM), respectively; and the adsorption property of heavy metal ions and organic dye contained in aqueous solution on the samples and magnetic recovery rate of the composite were studied. The results show that the main magnetic phase of Fe3O4 presents spinel structure, the Fe3O4/rectorite composite has well superparamagnetic, magnetism increases with the weight of Fe3O4 particles increasing, the composite has high magnetic recovery rate, and the adsorption isotherms of metal ions Cu2+, Zn2+, Cd2+, methyl orange and methylene blue from aqueous solution on the samples indicate the absorption capacity of the Fe3O4/rectorite composite is lower slightly than nature rectorite, but it is still very high.
