摘　　要：本文通过化学转化法即化学共沉淀法，分别研究了强酸性和弱酸性阳离子交换树脂的磁转化条件对相应所得树脂的磁性的影响，制得了磁性毫米级和微米级粒径的强酸性，弱酸性阳离子交换树脂。所得磁性树脂的磁性强，磁性物质分布均匀而且稳定，并保持树脂的原有特性。Magnetic cation-exchange resins prepared by chemical transformation method are described in this paper. The effects of the chemical transformation conditions on the magnetism of the resulting resins were studied. The magnetic strong and weak cation-exchange resins,mm -grade in diameter or μm-grade in diameter, were prepared. The obtained magnetic resins exhibit strong magnetism. The magnetism of the resin is well distributed throughout the resin particle. Meanwhile, the original exchange capacities of the cation-exchange resins used are maintained.
