摘要
磁性壳聚糖集成了壳聚糖螯合金属离子的能力和四氧化三铁的磁响应性,赋予了磁性壳聚糖吸附放射性污水中放射性金属离子能力,且具有可回收性和易再生性,使其在处理放射污水中效果显著。综述了纳米Fe3O4合成与磁性壳聚糖微球的制备方法,并讨论了在放射性污染水处理中的应用,最后展望了磁性壳聚糖研究趋势。
Magnetic chitosan microsphere,the combination of chelation capability metal ions of chitosan and magnetic response of magnetite,possess the characteristics of absorption of radioactive metal ions,recycle and regeneration,which makes it more effective when dealing with a variety of pollu-tion of water bodies. This paper systematically reviewed the synthesis of magnetic nanoparticle,preparation of magnetic chitosan microsphere,and their application in the field of radioactive contamination. Finally,the development of magnetic chitosan microsphere applied in water treatment research will tend to preparation magnetic chitosan with grafting chelation group,higher specific surface area and immobilized enzyme.
