摘　　要：木质素是一种有机高分子,大量存在于木材、竹材、秸秆、草类及其它植物材料中。但由于其结构复杂,导致应用受到很大的限制。有效利用好木质素这种可再生资源已成为科研工作者研究的出发点。木质素吸附剂是近年来木质素高值化利用研究的热点。文章在简要介绍木质素的化学结构及其分子修饰基础上,对木质素及其衍生物近年来在重金属离子的吸附研究进行了综述。Lignin is an organic polymer, and largely presents in wood, bamboo, straw, grass and other plants materials. However the application of lignin has been greatly hindered due to its complicate structure. Full utilization of lignin has served as the primary incentives for developing the lignin material by many researchers. Lignin absorbent is an important research topic for its high-value use in recent years. Based on the introduction of the chemical structure and molecular modification of lignin, the absorbing capacity of heavy metals for lignin and its derivatives were reviewed.
