Description
Summary:In this research, branched magnetic nanoparticles with dendritic amine groups were prepared and functionalized. These nanoparticles have a clear core–shell structure, uniform size, and high magnetization. The synthesized Fe 3 O 4 @SiO 2 /Branched by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), scanning electron microscope (SEM), Transmission Electron Microscopy (TEM), zeta-potential measurement, and vibrating sample magnetometer (VSM) Characterization of nanoparticles. The effects of different factors were studied, including pH, equilibration time, metal concentration, Fe 3 O 4 @SiO 2 /Branched dose, and temperature. The kinetic analysis showed that the adsorption process was successfully adjusted using the pseudo-second kinetic model. The adsorption isotherm data are fitted using a Langmuir model. The adsorption of metal ions on Fe 3 O 4 @SiO 2 /Branched is temperature-dependent and increases with the increase of system temperature, indicating the endothermic and spontaneous nature of adsorption. The maximum adsorption capacities of Pb(II), Cu(II), and Co(II) are 311, 204, and 146 mg/g, respectively. The Fe 3 O 4 @SiO 2 /Branched was regenerated and it was found that the adsorption capacity was not significantly reduced after repeated use for five times in the continuous adsorption and desorption cycle. Graphical abstract Highlights Fe 3 O 4 @SiO 2 /Branched nanoparticles were synthesized to remove Pb(II), Cu(II) and Co(II) ions from aqueous solution. Adsorption followed pseudo second order kinetics and Langmuir isotherm model. The preference ranking adsorption on Fe 3 O 4 @SiO 2 /Branched presented Pb(II) > Cu(II) > Co(II). The regeneration capacity of the Fe 3 O 4 @SiO 2 /Branched were tested.
