摘要:木质素是可再生的天然芳香族聚合物，其分子结构上的活性基团使其具有成为优良的绿色吸附剂的潜力，可用来吸附重金属离子、有机物及其他废水污染物、废气污染物等。本文首先对木质素的结构特征、应用进行了总结介绍；其次对木质素的提取分离方法进行综述，进而概述了木质素的改性及其制备吸附材料的研究进展；最后总结了当下木质素吸附材料的主要应用领域，并在此基础上对木质素的未来研究方向进行了展望。

Abstract:Lignin is a renewable natural aromatic polymer， and its active groups on the molecular structure make it as an excellent green adsorbent for adsorbing heavy metal ions， organic matter， and other pollutants in waste water and off-gas. In this paper， firstly， the structural characteristics and application of lignin were summarized. Secondly， the extraction and separation methods of lignin were reviewed， and the research progress of modification of lignin and the preparation of adsorption materials were summarized. Finally， the main application fields of lignin-based adsorption materials were summarized， and the future direction of efforts was looked forward to on this basis.
