摘　　要： 木质素结构中含有芳环、脂肪族侧链和许多活性官能团 ,具有一定的离子交换与吸附性能。工业木质素主要源于制浆造纸业的副产物 ,通过改性可以制备各种功能不一的木质素基吸附材料。本文综述了木质素的吸附性能和国内外木质素基吸附材料的研究进展 ,分析存在的问题和难点 ,探索今后的研究方向。 Lignin consists of both aromatic and aliphatic portions containing many active functional groups, which suggests some ion exchange and adsorption properties. Technical lignin is mainly obtained as a byproduct from pulp and paper industry. By modification, lignin can be utilized to prepare lignin-based adsorbing materials with different functions. The adsorption property of lignin and the progress in the research on lignin-based adsorption material are reviewed in detail. In addition, the problems and difficulties involved are discussed, and some suggestions on the research of lignin-based adsorption material are presented.
