Abstract :

Magnetite nano-particles (Fe3O4) and modified nano-cellulose with citric acid, urea and acrylamide were prepared using chemical method. Samples of Fe3O4 coated with the modified nano-cellulose were characterized by Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), Fourier Transformed Infrared Spectroscopy (FTIR) and Vibration Sample Magnetometer (VSM). Fe3O4 with modified nano-cellulose was applied to adsorb many radioactive ions such as Th232 daughters Ac228, Pb212, Bi212 and Tl208 radioisotopes from aqueous solution. The effect of contact time, PH and concentration of radioactive ions on adsorption process were investigated. High resolution gamma rays spectrometer of hyper pure germanium detector was used to measure the activity of radioactive ions before and after water treatment. The present work appeared that functionalized of nano-cellulose with Fe3O4 enhanced the adsorption process about Fe3O4 only. The prepared samples with modified nano-cellulose can be used at commercial level because low cost of production and no toxicity.
