英文摘要	Novel-modified magnetic multi-walled carbon nanotubes (MMWCNTs) were synthesized via evaporating acid purification and co-precipitation method. MMWCNTs were used for simultaneously removing lead and zinc ions from aqueous solutions. Transmission electron microscope, field emission scanning electron microscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy (XPS), and magnetization curve showed the morphology, composition, surface functional groups, and magnetic properties of MMWCNTs. Then, the adsorption effects were investigated by times, pH, and adsorbent dosages. The results showed that Fe3O4 of approximate 10nm successfully grafted on the surface of MWCNTs. The results of XRD, energy-dispersive X-ray spectroscopy, and XPS further confirmed that the iron oxides were Fe3O4. Adsorption data were analyzed with Lagergren pseudo-first-order, pseudo-second-order kinetic, intraparticle diffusion, and liquid film diffusion models. Langmuir isotherm model showed the maximum adsorption capacities as 67.25 and 3.759mg/g for lead and zinc ions, respectively. These results indicated that MMWCNTs may be a promising candidate for removing heavy metal ions from aqueous solutions.
