摘　　要： 探讨化学转化法制备磁性阴离子交换树脂过程中几个主因素对处理后树脂中 Ｆｅ２＋ 与 Ｆｅ３＋ 的含量及质量磁化率的影响，找出磁性树脂质量磁化率与 Ｆｅ２＋ ， Ｆｅ３＋ 比例之间的关系，确定最合适的制备条件．并利用粉末 Ｘ 衍射技术对制备的磁性树脂的磁性成分进行研究。 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.
