| 摘 要： | 采用共沉淀法制备Fe3O4磁流体,再与5A沸石复合制备一系列不同Fe3O4载量的磁性5A沸石,并对其进行X射线衍射、扫描电子显微镜、X射线能谱仪、振动样品磁强计等表征分析,测定了磁分离回收率及铜、锌、镉离子饱和交换吸附量。结果表明,Fe3O4微粒主要赋存于5A沸石粒间,磁性5A沸石具有良好的超顺磁性,铜、锌、镉离子的饱和交换吸附量随Fe3O4载量增加而小幅降低,但仍与5A沸石相当。Fe3O4载量为25%时,其饱和磁化强度、剩余磁化强度分别为13.817、0.351A.m2/kg,磁分离回收率为98.78%,铜、锌、镉离子的饱和交换吸附量分别为77.1、70.8、135.3mg/g。

| Abstract: | Magnetic influence of Fe3O4 was prepared by coprecipitation method,and then prepared magnetic 5A zeolite with different loadings of Fe3O4,the production were characterized by X ray diffraction,scanning electron microscopy,energy dispersive spectrometer and vibration sample magnetometer,the magnetic recovery rate and saturation exchange-adsorption capacity to copper,zinc,cadmium ion were also measured. The results show that Fe3O4 particles mainly occurrence between the grains of 5A zeolite,magnetic 5A zeolit... |
