The Study on Material Preparation and Adsorption Properties of Magnetic Smaller Sized Fe₃O₄ Load on Multi-Walled Carbon Nanotubes

Abstract:

On the one hand, accordingly to remove the surface impurities, we purified the prepared Multi-walled carbon nanotubes (MWCNTs) in our advance experiment; ferrous ions and iron ions in lye through the action of micro-filtration membrane to form smaller size Fe₃O₄ magnetic particles on the other hand. The prepared magnetic Fe₃O₄ with small particle size was loaded on the adorption point of the multi-walled carban nanotubes(MWCNTs) to form magnetic carbon nanocomposites. In order to achieve the best adsorption effect, the preparation temperature was improved in the experiment, and the influence of the ratio of ferrous ions to iron ions on the properties of the material was adjusted. The best adsorption properties of the composites were confirmed by X-ray diffraction and Fourier infrared spectrometer phase analysis. In addition, the application of this experiment to water treatment has a good effect on the copper ion removal.
