Chemical co-precipitation synthesis of manganese ferrite (MnFe2O4) nanoparticles as a magnetic adsorbent of lead
Herein, MnFe2O4 binary oxides, including various percentages of Fe3O4 were synthesized using the chemical co-precipitation method. In order to determine the physicochemical properties, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (SEM-EDX) analyses were used. Adsorbent dosage, pH of the solution, contact time, and adsorbate concentration were optimized during the adsorption process. It was found that the Langmuir isotherm model is the best kinetic model for adsorption. Finally, the mean adsorption energy, reproducibility, and spontaneity of the adsorbent were also estimated, which showed that the physical adsorption mechanism is dominant.
期刊介绍：
Main Group Chemistry is intended to be a primary resource for all chemistry, engineering, biological, and materials researchers in both academia and in industry with an interest in the elements from the groups 1, 2, 12–18, lanthanides and actinides. The journal is committed to maintaining a high standard for its publications. This will be ensured by a rigorous peer-review process with most articles being reviewed by at least one editorial board member. Additionally, all manuscripts will be proofread and corrected by a dedicated copy editor located at the University of Kentucky.
