This research work explored the synthesis and characterization of magnetic manganese ferrites using a simple combustion method. The purpose of creating the magnetic manganese ferrites was for their planned use as ozonation catalysts. Their magnetic properties allow for their recovery from the treatment system. Magnetic manganese ferrites were prepared by mixing manganese nitrate and iron nitrate in a stoichiometric ratio of 1:2. Polyvinyl alcohol was added to the mixed metal salt solution and the ratio of PVA: total nitrate salt added was varied from 1:1 up to 1:2 by weight. The resulting particles were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), tunneling electron microscope (TEM), and Ultraviolet-Visible spectroscopy (UV/Vis).
本研究工作采用简单燃烧法探索了磁性锰铁氧体的合成与表征。制备磁性锰铁氧体的目的是将其用作臭氧氧化催化剂。其磁性使其能够从处理系统中回收。通过将硝酸锰和硝酸铁按化学计量比1:2混合来制备磁性锰铁氧体。将聚乙烯醇添加到混合金属盐溶液中，聚乙烯醇与添加的总硝酸盐的重量比从1:1变化到1:2。通过X射线衍射（XRD）、X射线光电子能谱（XPS）、扫描电子显微镜（SEM）、隧道电子显微镜（TEM）和紫外可见光谱（UV/Vis）对所得颗粒进行表征。
