Description
Modified chitosan-coated nickel ferrite silica nanoparticles were prepared, characterized and experimented for the removal of U(VI). Adsorption amount was 125.30 mg g-1 at pH 5.0. The magnetic chitosan based composite could be successfully recycled from uranium aqueous phase. Finally, calculated data and analysis suggested that the adsorption behaviors of magnetic chitosan based nanoparticles can be explained by pseudo-second order kinetic model (R2 = 0.9915), which suggested the adsorption process was probably controlled by chemical adsorption, and langmuir model (R2 = 0.9816), which suggested the adsorption process was probably controlled by single-layer adsorption.
