Magnet chitosan (MCG) was prepared with water soluble chitosan coated on magnetite particles, which was obtained by coprecipitation of Fe 3+ and Fe 2+ in alkaline solution, and then cross-linked with glutaraldehyde. The adsorption capacity of Pr 3+ ions on the magnet chitodan was studied. The adsorption capacity of Pr 3+ ions on MCG better than on chitosan was found.The highest rate of adsorption still reached over 90% on MCG in lower pH. MCG can be reused five times,it's adsorption cap...
