自制了大孔球形纤维素基阴离子交换树脂(PSC-AN),并利用化学转化法成功制备了大孔球形纤维素基磁性阴离子交换树脂(PSC-MAN).对影响树脂质量磁化率的几个主要因素进行了探讨,实验确定最佳制备条件为:铁盐的配比为1:10,EDTA的浓度为0.005 mol/L.对树脂的结构和性能进行了研究,表明化学转化法制备大孔球形纤维素基阴离子交换树脂(PSC-MAN)磁性强,在碱液中相当稳定,树脂磁化前后交换容量分别为Q_前=1.33 meq/g、Q_后=1.16 meq/g,即树脂基的交换容量基本不受磁化过程的影响.

The spherical cellulose-based magnetic anion exchange resin was successfully prepared with chemical transformation. The main factors affecting magnetic susceptibility of the spherical cellulose-based magnetic anion exchange resin were studied and the optimum conditions were established. The structure and properties of magnetic resin were also tested. It indicated that the spherical cellulose-based magnetic anion exchange resin prepared with chemical transformation possessed high magnetic strength and was very stable in basic medium, and its exchange capacity kept unchanged during its magnetizing process.
