摘　　要：重金属离子污染是当下最严峻的环境问题之一。利用储量丰富、可再生、可降解的木质纤维资源改性功能化磁性材料得到木质纤维基磁性吸附材料,并用于去除水中的重金属离子具有吸附性能优异、易回收等优点,日益受到国内外研究者的关注。在简单阐述磁性纳米材料的基础上,重点介绍了国内外纤维素基、木质素基、半纤维素基磁性吸附材料的制备方法,归纳总结并比较了其对不同重金属离子吸附性质,探讨了木质纤维基磁性吸附材料在重金属离子污染去除中的应用并对其影响因素进行了分析,同时展望了木质纤维基磁性吸附材料的未来发展方向。Pollution by heavy metals is a serious environmental problem.Lignocellulose offers the advantages of high-capacity storage,renewability,and biodegradability,while offering excellent adsorption performance and being easy to recycle.As such,it is being increasingly used as a magnetic adsorbent for the removal of metal ions from polluted water.Starting with a brief description of magnetic nanomaterials,this review focuses on the preparation of cellulose-,lignin-,and hemicellulose-based magnetic adsorption materials,both domestically and overseas,summarizing and comparing their abilities to adsorb different heavymetal ions.In addition,the adsorption abilities and factors influencing the removal of different heavy metal ions are discussed in detail.Finally,future development directionsfor lignocellulose-based magnetic adsorbents are discussed.
