Manganese ferrite nanospheres constructed by nanoparticles were synthesized in high yield via a general, one-step, and template-free solvothermal method. The product was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscopy (TEM). BJH pore-size distribution shows that the sphere-like manganese ferrite particle was a porous structure with a narrow pore-size distribution. The investigation of magnetic property of manganese ferrite nanospheres reveals that the saturation magnetization is high, which showes an excellent ability for magnetic removal of chromium in wastewater.
