摘要

以改性的天然沸石为基体，应用磁性载体技术，使具有磁性的Fe,3,O,4,与改性沸石相结合，成功制备出可用磁性技术回收的壳聚糖磁性沸石复合体。采用X射线衍射、扫描电子显微镜、振动样品磁强计等方法对其进行表征分析，并探讨其对放射性核素Cs的吸附能力及磁性回收性能。结果表明：Fe,3,O,4,微粒附载于磁性沸石表面或相互聚集，与钠型沸石相比，磁性沸石的结构没有发生明显改变；磁性沸石对Cs离子的去除率随吸附时间的延长而快速升高，240 min以后升高趋势变缓，在16 h达到顶峰，其饱和吸附量为78 mg/g，饱和磁化率为23.773 emu/g；磁性技术回收测定其回收率为99.2%。利用磁性沸石作为吸附剂处理含Cs离子的废水具有应用潜力。

Abstract

Magnetic zeolite was prepared by combining modified zeolite with Fe,3,O,4, by a physical adhesion process based on magnetic carrier technology. The composition of the resulting material was determined by X-ray diffraction, scanning electron microscopy, and magnetization measurements. The adsorption capacity of the magnetic zeolite for Cs ions and the magnetic recovery rate were also studied. The results showed that the Fe,3,O,4, particles adhered to the magnetic zeolite surface or aggregated to one another, forming magnetic particulates. As opposed to the case of Na-zeolite, there was no change in the structure of the magnetic zeolite. The removal rate of Cs ions from the magnetic zeolite increased rapidly with an increase in the adsorption time, after 240 min, increased slowly. After 16 h, the Cs ion adsorption reached the maximum value. The maximum adsorption capacity for Cs ions reached 78 mg/g, and the saturation magnetization of the magnetic zeolite was measured to be 23.773 emu/g. The magnetic recovery rate reached 99.2%, which facilitated magnetic separation of the sample after the adsorption process. The magnetic zeolite prepared in this study has potential application for the removal of Cs ions from wastewater.
