Ferrites nanostructures have been prepared with flower-like shape, as novel cost effective dye removal agent to be used in water purification. CoFe2O4, and MnFe2O4 has been prepared via ethylene glycol (EG) mediated self-assembly method. The morphological properties of the as-synthesized nano-flower were investigated using transmission electron microscopy (TEM), and selected area electron diffraction (SEAD). Factors influenced shape of nano-flower, such as time, temperature, pH, and urea concentration has been studied. For water purification applications, it is clear that the as-prepared ferrites nano-flowers represent an excellent efficiency to remove polar red 390 dyes from water with efficiency with 46, and 96% for both of CoFe2O4, and MnFe2O4, respectively.
