摘要：
The optimum condition of preparation for spherical cellulose-based magnetic cation exchange resin with chemical transformation were found by orthogonal test, that is, impregnating the resin with a mixture iron salts solution that the ratio of Fe and Fe was 1:2 for 90 min at room temperature. Then on addition of sodium hydroxide which the concentration was 2 moL/L, the metal salts are converted to crystals of Fe3O4 which are uniformly contained throughout the pores and surface of the porous resin. Then spherical cellulose-based magnetic cation exchange resin was gained. The mechanism of resin magnetization was elementary discussed.
