| Abstract: | In the process of preparation of magnetic anion exchange resin by mains of chemical transformation,the main factors affecting the content of Fe 3+ ,Fe 2+ in D201 resin and magnetic susceptibility of magnetic resin were studied.The relation between magnetic susceptibility and the proportion of Fe 3+ and Fe 2+ was defined,and the optimum conditions of preparation for magnetic resin was found.The magnetic component of magnetic resin were tested by powder diffraction.Then the mechanism of magnetization was analyzed theoretically. |
