摘要
近年来,将壳聚糖及其衍生物作为重金属吸附剂的研究,受到了越来越多的关注。通过交联改性可明显改善壳聚糖的机械性能、酸溶性和吸附选择性。不同类型的交联剂对壳聚糖吸附剂的吸附性能有重要影响。通过大量文献调研和总结分析,较系统的回顾和总结了制备交联壳聚糖吸附去除水中重金属离子的研究进展和应用现状,并对其利用发展前景和研究趋势进行了展望。
In recent years, much attention has been paid to the research ofchitosanand its derivatives as adsorbent for heavy metal ions. Crosslinking modification of chitosan has become an important approach to improve its adsorption properties to heavy metal ions. Different cross-linking agents has an important influence on the adsorption properties of chitosan adsorbent. By crosslinking, mechanical properties, acid solubility and adsorption ability ofchitosan can be significantly improvcd. In this paper, the existing research related to synthesis methods of cross-linked chitosan and the absorption process of metal ions were reviewed systematically. In addition, the development potential and research trend of those kinds of materials were prospected.
