| Abstract | ||||
| BAGASSE fiber suspensions, obtained from the Egyptian sugar cane plants are used through one cycle of an in-situ processing to obtain superparamagnetic papers, bearing 5-13 wt% ferrite nanoparticles of iron oxide or mixed oxides of iron with cobalt and/or nickel. Oxidation of metal hydroxides, precipitated by alkali from metal chlorides and nitrates were oxidized using hydrogen peroxide. The products' properties of the magnetic paper formed were evaluated by characterization using XRD, TEM, and magnetic hysteresis measurements. Although a one-cycle process was used, the process yielded magnetic fibers containing nanoparticles of about 30-80 nm. Magnetic hysteresis-loops show that all products are super-paramagnetic with relatively high saturation values. | ||||
