Abstract

AbstractThe Co doped Li0.5Fe2.5O4 ferrites are successfully prepared by using sol–gel synthetic process. The resulting nanosample is characterized by using XRD and SEM technique. The x‐ray diffraction (XRD) analysis studies clearly suggest the formation of single phase nanomaterials. The SEM analysis indicates the formation of uniform and fine grains like morphology in mixed‐metal oxides. The results of combustion synthesis elucidate that the fuel to oxidizer ratio is the most effective factor for the formation and surface morphology of mixed‐metal oxides. The synthesized Co doped Li0.5Fe2.5O4 ferrite is used for the adsorption studies of methyl orange dye by batch experiments. It is found from the adsorption studies that the removal percentage of Methyl orange is much better. Li0.5Fe2.5O4 particles are good adsorbent materials for removal of methyl orange dyes as compare to the Co doped Li0.5Fe2.5O4 nanopowder. However, the adsorption capacity of Li0.5Fe2.5O4 can be lower by doping with cobalt.
