Statistical Study for Optimization Magnetic Property of Modified MNPs (Fe_3 O_4/PEG(PVA)) Synthesis by Co-Precipitation Method |
|
| چکیده انگلیسی مقاله |
IIn this research, MNPs were fabricated and coated by the co-precipitation method. The study of this process was performed in a two-level factorial design framework. The effect of a polymeric agent, the strength of the alkaline solution, and the temperature on the magnetic properties MNPs were studied in this design. the structure, morphology, size, appearance, and magnetic behavior of modified MNPs were investigated using XRD, FT-IR, TEM, and VSM. The results obtained from the spectra show the modified MNPs have superparamagnetic behavior with high saturation magnetization ( ) and small coercivity ( ). The mean size of coated MNPs was determined 10 nm, saturation magnetization 60.98 emu/g, and magnetic coercivity 8.26 G. |
