| Abstract: | The main factors affecting the preparation of magnetic cationic exchange resin by chemical transformation were experimentally studied in detail. The results indicated that the content of Fe 3O 4 and magnetic susceptibility for the magnetic cationic exchange resin are obviously influenced by such factors as the ratio of Fe 3+ and Fe 2+ and concentration in the mixture, dipping time and temperature, the concentration and dosage of NaOH solution as well as the transformation conditions and so forth. |
