摘要：
Waste ferrous sulfate, which is an industrial by-product from titanium dioxide production, leads to a serious environmental pollution and waste of resources without being utilized. To enhance the utilization value of waste ferrous sulfate, we proposed a new idea that take the waste ferrous sulfate as the main starting material to synthesize cubic inverse spinel copper magnesium ferrite nanoparticles (CMFNPs) via solid-phase reduction method. The properties of the as-synthesized CMFNPs were investigated via using various analytical technologies such as thermogravimetric-differential thermal analysis (TG-DSC), powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and field emission scanning electron microscopy (FESEM) equipped with energy dispersive X-ray (EDX) spectrum. The results indicate that the synthesized CMFNPs display like-spherical structure with the average diameter of similar to 70 nm. Magnetic analysis demonstrate that the CMFNPs have have a high saturation magnetization of 53 emu/g, coercivity of 0.18 kOe and remanence of 8.2 emu/g. Additionally, the CMFNPs belong to superparamagnetic properties. Hence, the synthesized CMFNPs not only makes efficient use of waste ferrous sulfate but also are valuable to be applied in the magnetic material.
